Ender 3 V2 RPI and Display Drawer

thingiverse

Update 06/18: I printed this design and had some clearance issues with the lid. Please download and use the latest drawer design that fixes these issues. Please be patient -- this is my first published design This is a remix of ma77morris's display drawer. Because of the complexity of that model, I built this completely from scratch but still would like to give credit for the original idea. I liked the concept but there were a few things that I adjusted to make it better for my purposes: 1) 55mm tall instead of 40mm. This will require raising your printer. I already have to raise mine for my motherboard and PSU covers so I figured I'd increase the height of the drawer to match. Also, I had a hard time getting the camera cable for my RPI 4 bent around the fan recess so this helps greatly with that 2) Revised venting. This should print easier without support and also work better. With the drawer pushed in, there is venting underneath the 40x40 due to extending 15mm lower. With the drawer pulled forward, the entire back of the drawer acts as a vent. 3) 2X 40x10mm fans. I don't necessarily think anything benefits from this but I had a spare one sitting around 4) Hexagon design on the front. Depending on the infill, this can help reduce filament required for printing while still adding strength. It also looks pretty cool. I included a knob that is locked into place when attached. 5) Ease of print improvements -- the only support which is needed is the rail that is used for the drawer guide (right side). Everything else should print without support as long as your printer does bridges halfway decent. 6) Reconfigured cable access holes. I added an additional access to the right side to allow for a RPI camera to be run out the other side. I also moved the primary cable access to the side instead of the bottom. Because the drawer extends lower, this should help avoid binding while opening and closing. This should work with the original lid. I didn't redesign that although I may in the future to match the style of the new drawer.
