2x2020 50mm Hefty Foot

Some time ago I needed to replace fans under mobo and PSU. To do it, I needed 50mm clearance, so I designed that Hefty Feet.

You can use it in 3 ways:
- just slide them in to profile
- bolt to profile with 3x m4 nuts and screws (min lenght 15mm)
- bolt down to surface with 5mm countersunk screws

I printed them with 10% gyroidal infill and pour resin inside with steel shavings filler.

Ender 3 series PTFE-to-Creality Direct Drive Extruder Arm Conversion

Since humidity is an issue in my area, I use Rubbermaid 21 cup dry boxes with a reverse Bowden setup on all my printers to minimize the filament's exposure to the air. My Ender 3 Pro is setup for direct-drive extrusion. The stock Creality extruders (plastic and aluminum) don't have a threaded inlet for a PTFE fitting. I'm not content with using a stop at the top 2020, which leaves a good amount of filament exposed, subject to getting brittle, causing breakage. I designed this glue-on conversion for the Creality extruder arms and will work with any PTFE fitting that use the M6 threaded ends.

My top-most criteria was to have it strengthen the plastic version of the Creality extrusion arms, hence the thickness or height of the conversion piece. I also wanted to make sure torque on the PTFE fitting, while the hotend was traversing the X-gantry, wouldn't cause the conversion to loosen up or break due to flexing.

I decided to tap the threads instead of designing them in. Ample reinforcement has been added around the hole so that tapping won't break into the infill. With this method the size and shape of the threaded hole is guaranteed regardless of the filament used and the accuracy of the printer.

If you don't have an M6x1.0 tap, and aren't interesting in acquiring one, you can make one by:

1 - filing two opposing grooves along half the length of an M6x1.0x10+mm screw with a jeweler's file

2 - running it in and out of the hole a little at a time, until the threads are cut all the way through the hole.

15% infill with a Grid pattern is ample as long as you use at least 4 walls (perimeters) I recommend 6. 5-minute epoxy and small hobby clamps will secure the conversion piece to the topside of the extruder arm, which should be done with the arm removed from the extruder. Make sure no epoxy gets into the PTFE threaded area or in the filament hole of the arm. Leave overnight to fully cure.

The two extruders shown are the plastic model that comes on the Creality Ender 3 series and the red anodized aluminum one (on my Ender 3 Pro) that comes with the Creality direct drive kit.


Ender 3 (Pro) Direct Drive Dual Gear Extruder Mount

Direct Drive and Dual Gear Extruder mount for Ender 3 (Pro).

I bought a [Dual Gear Extruder](https://www.amazon.com/Bigtreetech-Extruder-extruder-Ender3pro-Filament/dp/B08D9CNHVN?&_encoding=UTF8&tag=r2j3d-20) and a [Direct Drive Extruder conversion](https://www.amazon.com/Extruder-Conversion-Printer-Creality-Aluminum/dp/B08YN6B5TN/?&_encoding=UTF8&tag=r2j3d-20) kit for my Ender 3 Pro knowing they wouldn't work together out of the box.

So I designed a mount to make them work together. The only thing you need to mount everything with this mount is a couple of [M3 bolts and nuts](https://www.amazon.com/Stainless-Assortment-Precise-Beautiful-Printed/dp/B0714FLXND?&_encoding=UTF8&tag=r2j3d-20);

- 2x M3x20 to fix the mount to the Dual Gear Extruder
- 2x M3x8 to fix it all to the Direct Drive
- Extruder conversion
- 2x M3 nut to work with the two M3x8
- 1x M3x12 to fix the spring mount instead of the original M4
- M3 washers (optional)

Make sure you fix the spring holder and then the mount to the extruder first with the M3x20 bolts.

Unfortunately It isn't possible to change tension on the spring with this setup so make sure you test the Extruder tension before without tensioning the spring on the extruder arm. With the right spring you don't need to adjust the tension. If needed you can fill in the space needed with a few washers when mounting.

For strength I used 4 outer wall lines with my 0.4mm nozzle and fill-density of only 15%

Assorted Tool Tray, Gridfinity 2x4 base

This is a tray I doodled for holding all of the usual tools for working on my 2020 based Hobby CNC systems, Laser etcher, 3D printer, etc. It's based on a 2x4 Gridfinity foot print. I added 10mm magnet holes for variety ( I had a bunch). Socket holes on the left fit most 1/4" square drive sockets and Hex bits. Parts tray in the center. Then L wrenches and hex driver holes on the right, as well as a spot for a mini adjustable wrench, and pair of nippers. All holes are intended to fit the tools loosely. I don't like having to wrestle the tray for a tool while I'm holding something in place.

Ender 3 Tool holder - Gridfinity

Since my enders live in enclosures now, I can't mount the tools on them anymore.  I remixed the tool holder I used into Gridfinity format

Direct Drive adapter v12.stl

I remixed this direct drive adapter for my Ender 3 V2 from this thing:

I added some extras to fit my printer better:
- cable guide + ziptie bracet
- some structural braces
- small cutout for extruder wheel

Length fits a briss fang with 4020 fan ontop.

Ender 3v2 x-Axis Tradfri Remote Mount.stl

Prints without supports. There's a pocket inside of the model to insert a 10x2mm magnet, remote could be glues in place as well.

The remote mount slides over the x-axis belt tensioner from the left side and is only friction-fitted.

To find the toggle threshold just home your printer and move the hotend to the right bit by bit until the remote gets pressed. I advise moving the x-axis back a few milimeters as the mount could be deformed with constant force after the printer has been turned off.
