This is a remix of Ender 3 V2 Drawer replacement from Thingiverse. I've remixed it to fit my setup:
RPI4 with POE+ hat
Pi Cam cable coming out the back of the RPI.
Hidden nozzle tray

---

I've been meaning to mount my RPI in the drawer section of Ender 3 v2 but wasn't able to find something that ticks all the boxes. So I watched some guides on Fusion 360 and made this remix. I've made the following changes:

  1. Lowered all RPI mounting studs, so there's enough space to put a RPI with POE+ hat in there upside down.
  2. Removed 40mm fan mounting bracket to make sure RPI has enough clearance. Fan grill is still there.
  3. Made a cutout for the Pi Cam cable coming out right behind the RPI. Position of it is assuming the RPI is upside down.
  4. Removed the right side 4040 rail cover that's popping out so I can keep the hidden nozzle tray there.
  5. Removed the mounting pillars on the lid.

I'd recommend printing in PETG just in case, RPI4 with POE+ hat runs pretty hot and I have 2 other RPI with POE in PLA cases that's super warped. Wouldn't want a section of my Ender 3 v2 to be warping after some time.

 

Notes:

You need to rotate both models when bringing it into slicer.
For base:

  1. Rotate it bottom down.
  2. Only support it needs is for the rail at right and back side, and the hooks on top. I just use normal support everywhere with 78 degree overhang angle. Then use support blocker to block out supports in the tiny holes, they don't need support.

For the lid:

  1. Rotate it so it sits vertically on the print bed. Look at last pic for reference. That way you can print with least amount of support.
  2. Only support it needs after you rotate it vertically is the left side curve. I just used the custom support plugin in cura to do that.
  3. If you rotate it vertically like I did you're gonna want to print with brim. 8 brim lines did just fine for me.
