Ender 3 Max Neo Pi Drawer

thingiverse

This is a slightly revised version. I was luckily enough to find the Creality model for the drawer so my model was a direct edit of the Creality model. The issue is most 3d printers are not perfect and the drawer was tight. Even after printing the revised version the drawer was tight along the back of the drawer and needed a few minutes of sanding to adjust the fit. In the original version the default knob did not fit so that was adjusted at well. Complete replacement to the Ender 3 Max Neo tool drawer to hold a Raspberry Pi 3, Buck Converter and Relay. Design of the tool drawer should work for Ender 3 v2 as well. The design is intended to use the original "case" for the tool drawer but for my method of implementation holes need to be drilled into the case for wire routing. A drill pattern in included in the images. Wire routing images are also included. Recommended Printing orientation displayed in images.
