I am finally releasing this model after a few fixes. Design was influenced by Vaunt's Tiltbox. This was done on tinkercad so there is no step file. I am moving on to learning Onshape so I will no longer be working on this model. 

Not a perfect model but I've used it for the last 6 months with no issues whatsoever.

This was printed on a Prusa mini+ (180 x180mm bed)


Item List/Notes: 

- Raspberry pi Pico
- 1.3 OLED SH1106 https://www.aliexpress.com/item/1005004146596540.html
- Gateron KS 27 low profile red switches lubed with generic GPL 205
- 10 X 2 magnets with hot glue/JB weld
- M5 x 5mm  screws  and nuts
- Micro to USB C 3.1 extender   https://www.aliexpress.com/item/1005005282250054.html
- I highly recommend using some JB Weld to stick some parts the top plate to the middle for extra durability.
- GP2040CE Firmware
Please visit https://gp2040-ce.info for more info, installation and wiring guide. 
-Buttons are slightly remixed (non-standard size) from Pett-J https://github.com/pett-j/Choc-Button-Caps/tree/main/Choc%20V2 to fit into my build as I am too lazy to go back and make some changes
-You can tighten the top plate and middle modules with some clamps as it can be a bit tight.  Might as well add some adhesive while you're at it! 
-KS 27 soldering pin helper will fit by inserting one pin in and wiggling left and right for the second pin. 

 


Print settings:
0.2 layer height standard prusaslicer settings
-Infill: Support Cubic at 25%
-Printed in PETG with Duramic3D Filament 
-Organic Support for Middle Left module
-Printed on a texture PEI sheet as it looks better and hides some layer lines if calibrated
