BEHOLD! THE INCREDIBLY LARGE TOME FOR PLAYING DUNGEONS AND DRAGONS!

And don't forget to take a look at my [Smaller Tome](https://than.gs/m/1124906) in case this is too big.

**Strap remix now available! That's right! Your Dungeon Master Tome can now be a "Book Bag"!!!** Download strap components [here](https://than.gs/m/1322963). Make sure to print print _Book Back_Strap.stl_ and _Pages_Strap.stl_ to be able to attach the strap!

**Update August 14, 2024:** Uploaded _Plain Cover.stl_ and _Dice Tower Part1_Lower tolerance magnet holes.stl_. The _Dice Tower Part1_Lower tolerance magnet holes_ file has increased tolerance on the magnet holes under the lip that hooks onto the front cover in case people struggle to get magnets inserted in such a tight space.

**Update August 11, 2024:** Uploaded _Dice Tower2 v2_ which has a lower tolerance for the magnets. Because of the little room there was to press-fit the magnets in, I've made it so you can just slide them in and use glue to keep them in place. I also updated the shape of the door of the dice tower.

**Update August 10, 2024:** Uploaded some lower tolerance hinge links for those who have difficulty snapping in the originals.

Now, before you get all excited, I highly recommend you read the ENTIRE description (with some exceptions) before starting your prints, just to be sure you don't have any regrets. (Who knew you'd be reading a tome in order to print a tome?)

-------------------------------------------------------------------------------------

Various inserts for the tome are available [here](https://than.gs/m/1116466).

**Don't forget you have access to other [custom front covers](https://than.gs/m/1131069) for this tome!**

-------------------------------------------------------------------------------------

**Disclaimer:** _The design was inspired by a friend who asked if I could make a D&D book for her to gift to someone. She knew nothing about D&D and neither did I. So I did some research and spoke with individuals who have played the game to get some ideas of what one might like in a tome like this one. So, if you have any feedback at all or any ideas on how the design can be improved or any additions that I could add to the book, please share! There will be a good chance you'll see some welcome changes if you do._

_This specific model's size practically utilizes the entire volume of my Bambu Lab X1-C. This means it was designed to fit on a 256x256 print bed. If you wish to attempt to scale things down, take a moment to visit the _Scaling_ section below before you decided that this is the direction you wish to go. I will be designing a smaller book for D&D, so you may have to be patient while waiting for that to come out if your print bed is too small._

_When specifying dimensions, they will be stated in terms of width x height x depth_

-------------------------------------------------------------------------------------

**Features:**
- Inserts for this tower were designed with "units" in mind so individuals can remix inserts according to their desires (Similar to gridfinity, but with different dimensions). Each unit is 30.5x30.5x25.2mm. So if I made a 1x1x1 insert, it would occupy 30.5x30.5x25.2mm. _Note: Make sure to incorporate tolerances when remixing inserts. I usually add a 0.2mm tolerance to each side, so the true measurement of a 1x1x1 insert for me would be 30.1x30.1x24.8mm._ 
- This model includes models for a dice tower that magnetically attaches to the book cover (See images for details).
- The dice tower was designed to fit in the tome in two different orientations. When folded, it will occupy a space of 4x3x2 units. When open, it will occupy a space of 4x6x1.
- The dice tower includes a door that opens to ensure dice land in the book and not on the floor (See images for details).

**About the Hinge Links:**
- The tolerance of where the hinge links clip into the book/dice tower are VERY tight. This is on purpose to ensure there isn't a lot of wobbling when opening and closing the book and helps to ensure longer durability of the hinge mechanisms. However, because of the way they were designed, you can scale them if you find the default thickness of them is too difficult to get snapped in. Just be sure to only scale them on the Z axis.
- Lower tolerance hinge links have been provided in case you feel iffy about scaling them. If you don't have man-hands like me, you might consider printing the lower tolerance hinge links for both the book hinge and the dice tower hinge. You should still get a nice fit.
- Because of the way the hinge links were designed, if they wear out or get too loose, you can easily print new ones and replace the old ones.
- You'll notice on one end of the hinge links, the hole is incredibly small. This is on purpose. The small hole is only 0.2mm thick before changing to the diameter that you see on the other side. I've found, when the plastic deforms when connected, it hugs the little "pins" and helps keep the hinge link from rattling. I've found this gives the book a more smooth and sturdy feeling when opening and closing it. If you're printing with something other than PLA, you might want to consider changing the link slightly according to your needs.

-------------------------------------------------------------------------------------

**Printing Instructions:**
Required Hardware:
28 - 6x3mm magnets (Yes, you'll need 28 of them... lots of magnets. Fortunately, you can usually buy a pack of 50 or 100 for $5-$10)

Supports? NEVER! GO TO HELL!
Brim: Recommended for all parts to avoid warping.

All models should be oriented in the way they were intended to be printed.

_What to print:_
- Book Front Cover - x1
- Book Back - x1
- Book front Hinge Interface - x1
- Pages - x1
- Long Hinge Link - x2
- Short Hinge Link - x2

Optional dice tower:
- Dice Tower Part1 - x1
- Dice Tower Part2 - x1
- Dice Tower Hinge Link - x2

The 3mf file provided was sliced in OrcaSlicer and has recommended configurations for printing each piece of the main tome.

-------------------------------------------------------------------------------------

**Assembly:**
[Video Instructions](https://youtu.be/_RWcHtnQimg)

All magnets should have a press fit tolerance. However, because of the different variations of printers out there, you may find you need to glue yours in or you may have to use brute force. _**Note**_: When installing magnets, be extra sure you're installing them in the proper orientation so they attract each other. I've made mistakes and don't want you to repeat them.

The Book Front Hinge Interface is meant to be glued into where the book binding would be on the front cover. It's designed so, if you try to place it incorrectly, it won't fit right. (I'm considered implementing some sort of fastening implementation to attach the hinge interface to the front cover. So if that's one of your gripes, stay tuned).

Glue the pages onto the book back.

When snapping in the hinge links, it is recommended that you snap the hinge links into the _Book Back_ portion of the book, first, before snapping them into the _Book Front Hinge Interface_. I've just found it easier to do it in this sequence.

If you feel like the hinge links are WAY to thick to ever have a dream of fitting in there, you're not alone. I rely on plastic deformation to occur when snapping them into place. Because the infill is still somewhat hollow, there is slight movement in the plastic as you press the links into their designated locations. I've found myself man-handling the things before and it can be frustrating if you just can't get them in. If you can't seem to get them to snap in, You can print some hinge links with the Z scale adjusted so they're a bit thinner.

Once all hinge links have snapped in, the assembly of your Dungeon Master Tome is complete! Now all you need to do is choose from the available inserts and customize your storage!

-------------------------------------------------------------------------------------

_**Scaling** (if you dare) *don't read this if you don't plan on scaling*_
_Disclaimer:_ If this starts to seem a little too complicated for you, rest assured I will be coming out with a smaller tome for lighter D&D users, so you can just wait for that if you'd like. It will fit smaller print beds.

Now, because of the magnet holes, any scaling will also scale those holes. So you'd have to scale it in a way to where you can use 2x4mm magnets or maybe 3x1mm magnets. It doesn't have to be those sizes specifically, but just consider the size of magnets you might be able to use, and scale the model accordingly. Yes, this means you'll have to do some math to know what percentage to scale it. You'll most likely have to uncheck "Uniform scale" (or similar setting) because there's a good chance your x, y, and z scale percentages will be different to get your desired results.

**IMPORTANT**: _Once you determine your scale percentages, you'll want to use the same scale numbers for every part you print. **BUT BE CAREFUL!** The orientation in which everything prints is not the orientation it will be in when the model is assembled. For example: The **Book Front Hinge Interface.stl** file is meant to be printed on its side. So, given the shorter axis is in the Y direction, if you scale the **Z** axis of the book to 50%, then you'd scale the hinge interface's **Y** axis to 50% instead of its Z axis._

Dice Tower Part2 is a print-in-place portion of the dice tower that includes a door that hinges open in order to ensure rolled dice make it to the tome from the tower. The tolerance I've given to each edge is about 0.2 mm, so keep that in mind when scaling down. If your printer can handle a tolerance of 0.1mm, then scaling might just work for you.

**Update August 12, 2024:** Added some inserts that I had designed as a part of a personal project. Card Insert2 was created to prevent D6 and D4 dice from falling in the middle chamber.

The inserts provided here are sized for the [Dungeon Master Tome](https://than.gs/m/1116436) I designed.

Feel free to remix your own inserts to fit my tome.

The dimensions specified in each insert is in "units". Each unit is 30.5x30.5x25.2mm (Not including tolerances).

So if I wanted to make an insert that is 3x5x2, then, incorporating a 0.2mm tolerance on each side, the dimensions would be:
(((30.5 * 3) - 0.4) by ((30.5 * 5) - 0.4) by ((25.2 * 2) - 0.4))mm

The "Cut" inserts were designed to fit on the top row of the tome. Because of the way the tome closes, clearance had to be made for the lid. So if you know your insert is going to be at the far end of the tome, you'll want to add a similar cut.

The dimensions of my cuts are 13.4mm from the edge and the angle is at a 45 degree angle.

There should be no problem scaling these if you find the fitment to be a little tight.

It's a giant pen!! What more could you ask for!!??

The "pen cartridge" needed for this giant pen is [a simple Bic pen](https://a.co/d/dMPZf4O). Refer to images for what the pen looks like.

This can be printed on a 180x180x180 build plate! That means it can be printed on an A1 mini or Prusa mini! What's more, it does not require an AMS or similar multi-color system to print!!

**Update July 31, 2025:** The clearance was too tight on the pen holder part. Updated pen tip, spring, and pen holder to increase the clearance so it clicks more easily.

**Update July 25, 2025:** Added multi-color option with "BP" on the pen. Also made adjustments to the outer shaft and pen clip housing so the z-seam aligns together more closely.

**Printing Instructions:**
The 3mf file provided was created using Bambu Studio and should have the following settings already configured.
- Layer height: 0.2mm
- Supports: Nope!

_Spring:_
The slicer is most likely going to complain and warn you about floating cantilever. You can ignore this.
The spring has built-in supports that are meant to be removed.
It is also recommended to print the spring in something other than PLA. PETG or similarly durable filament will work fine.
- Infill: 100% (To add stiffness to the spring)

**Assembly:**
Please refer to the assembly guide to assemble the pen.

For removing spring built-in supports, refer to the linked YouTube video.

After assembly, if you find it difficult to actuate the click, you could add some lubrication to the portions of the clicker that rub together to make it easier.

Medium sized funnel for liquids. Comes with clip-in filter/strainer for separating undesirable items from liquid.

The filter piece contains 0.8mm holes but these may differ in size depending on your printer setup. I found that printing the filter on a raft lead to more regular filter holes.

This modular hydroponics tower lets you grow a large amount of plants without the need of  lots of room. Each module fits 3 50mm (2 inch) pots and has the water tube running up the middle. Just stack as many modules as you require. 

Each module is designed to fit 3 M3x4x5 heat-inserts and bolt together using M3 x 6mm bolts. 

I designed this to fit on a small 3D printer, with a build area required of 170 x 170.

At the bottom of the stack you need the Base with a 16mm barb fitting and the optional base clamp (to clamp to the other side of a container lid) and attach it to a submersible pump.

At the top you push in the shower head and bolt on the lid. I drilled out the holes of the top module to 4.5mm to fit in 3 heat-inserts to make this secure but it does function fine without the lid bolted down. 

Have fun growing!
