Discover the world of 3D printing at Thangs.com with our robust and user-friendly 3D Craft Hub Refillable Spool, an innovative solution in the 3D Printer Parts & Accessories and Filament Management category. Joining the refill revolution not only reduces plastic waste but also boosts your 3D printing experience by providing a reusable, reliable spool specifically made for filament refills. This brilliantly designed refillable spool is touted for its strength, speed and ease of use, thus making it an essential addition to your 3D printing toolkit. 

Our refillable spool's standout features include a threaded assembly that guarantees secure and sturdy connection between the two halves, a uniquely slotted design that significantly cuts down on material usage and print time, and a standard size fitting that accommodates most 1kg refills and fits standard spool holders. 

When it comes to printing this refillable spool, we recommend using PETG due to its superior strength and durability, although PLA+ and standard PLA can be viable alternatives. Excitingly, the printing process doesn’t require any supports and offers optimal results at 0.28mm layer height with three walls, striking the perfect balance between speed and resilience. Explore the images for a visual overview and start the journey towards more efficient, sustainable 3D printing with Thangs.com. Step into the future of 3D printing and say goodbye to single-use plastics with the 3D Craft Hub refillable spool.

The Ultimate Refillable Filament Spool (Threaded)

Filament Spool.STL

This is a variant of my [tunnel block](https://than.gs/m/853821) with a flat bottom meant to be used as a baseplate:
- features rabbit clips and sockets to allow multiple basepaltes to be locked together
- features pockets for rubber feet, default setup for 6x2mm feet (0.5mm deep pockets)

These are designed for a desktop grid module that you don't want to accidentally slide around.

Suggested slicer settings:
- split the baseplate itself from the clip sub-object
- the baseplate works well for me using 5% infill (3d honeycomb), 3 top/bottom layers, and no support
- the clip seems best printed with 2 walls, 0 top/bottom layers, and 0% infill; it should be all wall paths

I've also uploaded a [1u-tall version](https://than.gs/m/861830) that is just a grid of Z-holes with the same rabbit clip sockets.

The blank one can be used with the help of TinkerCad or Fusion 360 to place an SVG on the 3 sides.  Then print away!

[Printy Panels](https://than.gs/m/1056203) compatible with [Zack Freedman's Gridfinity system](https://than.gs/m/60925).

**Options**

- **Basic Panel** - Uses minimal filament
- **Weighted Panel** - Squeezes in a few more bin ports with a thicker base
- **Magnetic Panel** - Includes holes for 6x2mm magnets or M3 bolts


**Printing**

- All parts can be printed without supports.
- Add a brim if curling is an issue.
- Use large 0.3mm layer heights for quicker prints that are still strong.
- Use PETG, ABS, or strong formulations of PLA. Silk, woodfill, and matte PLAs are NOT recommended.


**Loose Connectors?**

If your connections are too loose, try one of the following:

- Add a slight fuzzy skin (0.1mm variance) to the connectors. This will essentially make the connectors a little thicker without altering their overall dimensions.
- Increase your extrusion multiplier so that the connector walls are slightly thicker.
- Increase your print temperature slightly - this often has a similar result to increasing the extrusion multiplier.

I personally designed this to hold some small note block. This works in general with parallelepipeds.
A spring is required to assemble.
I also designed a extension for the mobile part, if you don't plan to leave it without anything inside it will work with just two pieces. 
To use the extension is required a 2.5 M bolt and nut.

Gridfinity 2x2 holder for sticky notes! I was surprised to find out that post-its fit perfectly inside the 2x2 footprint. This bin fits sticky notes of the standard 3" size (which is just under 77mm).

Prints with no supports, works with all your other Gridfinity stuff!

Gridfinity Post-It Sticky Note Holder

Gridfinity - Post-It Holder.stl

Riser blocks for gridfinity designed to allow routing cables underneath and around other gridfinity modules.

The 21mm tunnels are large enough to push USB A connectors and barrel jacks thru. However AC wall plugs will not fit (e.g. most NEMA connectors) nor will larger IEC connectors (like the ever immortal C13 connector popularized by PC power supplies).

Originally motivated when gridfinitizing a battery charging cabinet.

Provided many likely model sizes for convenience, but if you need other dimensions, the OpenSCAD model is available here: https://github.com/jcorbin/gridfinity-risers

Made based on modules from https://github.com/vector76/gridfinity_openscad .

I've also made a [standalone baseplate](https://than.gs/m/859253) variation of this block if you don't want to print out a base frame.

Gridfinity Tunnel Risers

tunnel_riser_6x5x4.stl

Gridfinity bin designed to hold 16 medium size binder clips.

Couple notes:

The shape triangular part of the binder clip isn't very consistent so the pegs that hold them in place are a bit undersized.

I've also included the F3D file if you want to make changes. I don't have much experience with Fusion 360 and this was one of my first attempts so don't expect the most user-friendly file though .

These are perfect for storing small parts and long, thin objects like needle files, and you can stack them as high as you want! The inner surface has a generous scoop to make retrieving parts easy, and the tab fits 12mm label-maker tape.

I've provided a selection of different sizes and divider counts, to give you OPTIONS! Note that none of the compartment sizes overlap - there isn't a two-compartment 4x1 bin because you can just use two one-compartment 2x1 bins.

Dimensions in file names are Width x Depth x Height. Width and Depth units are 42mm grid slots, Height is in 7mm units. A Prusa i3 Mk3S can fit a five-unit-wide bin on its plate.

Note that two-unit-high bins don't have labels - they would cut too far into the usable storage area.

Brims and support are not required, and these can be printed in any filament with an 0.6mm or smaller nozzle. Wider bins can curl, so maximize your bed adhesion if you're going big!

**Gridfinity Tips!**
- All storage blocks are compatible with all baseplates!
- Most storage blocks are stackable!
- You can add 6x2mm magnets to the corners! They won't magnetize the contents.
- You can also use M3 screws in the corners. 

Gridfinity was inspired by Alexandre Chappel's ModuBOX system, which is found at https://www.alch.shop/shop/assortment

Gridfinity Divider Bins

Divider Box 2x1x6 5-Compartment.stl

I wanted to make a large, printable, modular shelving unit to take advantage of gridfinity and honeycomb storage, so I designed this! I originally designed it to use M3 and M5 screws and heat set inserts, but have also included alternate files for all M3 screws screwing directly into the plastic. The sides, back, and bottom need to be printed on edge diagonally to fit onto a 256x256 print bed. The hex side walls should be printed flat on the print bed. Print them first, and then when printing the sides and back, put a pause command in the slicer to stop just before it starts the giant bridge and slide the hex walls in. They have an orientation, the hex holes should be larger on the inside of the shelf than the outside. The bottom shelves needed to be split in half to be printable, and I made the gridifinity baseplate print seperately and be pushed on to the shelf so that you wouldn't need any support. The sides have mounting holes for the shelves at the top and bottom for flexibilty. Clearance holes have a diamond top and bottom to avoid the layers interfering with clearance, holes that are being screwed into or are having heat sink inserts mounted in them don't have this to maximize surface area.

I've attached a fusion archive of the original project file. Feel free to tweak it for your own hardware or make whatever changes you need!
