Raspberry Pi 4 Case by mccawley74

Raspberry Pi case based on a gaming rig.
UPDATE: Added files to make this case accept a Pi 3
I do not have a Pi 3, so it is untested, but should work.
PSU_Cover_Solid_Pi_3.stl
case_back_Pi_3.stl
Rotating retractable feet.
Removable front screen with space for a filter.
Slide in side covers in both solid (with vent) or windowed (Rabbited for the thickness of an old CD case. Score one of the CD case panels with a razor and snap to shape)
Two PSU covers (what would be the PSU). One solid and one for a USB panel mount, so you can insert a USB Drive internally in the case. I soldered up an old USB DOM and printed a SSD like case for it (included if you're interested)
The back panel takes an RJ45 keystone jack like you would find at Home Depot. to extend the plug outside the case. (See images)
The power button takes a small microswitch glued into the power button housing. (See images) You will need to sand/cut to length.
There are two sets of feet, Solid and retracting. For the retracting, after inserting the foot into the peg, apply a tiny drop of glue to the center post and hold in place on the bottom of the case where you want the foot. I'd also wiggle the foot back and forth to keep it from gluing in place.
The Pi Board holder is much like an actual case. Mount the board to the board panel with tiny screws, and insert into the case. It aligns with notches that you might need to sand a little to fit.This design allows room for cables to be brought down to the bottom section.

NOTES:
I soldered a small breadboard to connect the three fans together and connected that to the Pi 5V connector
Power button is connected to 5 and 6 (GPIO3 and GND) for controlling the power search google for "Raspberry Pi button wake functionality"
This case fan combo pushes a lot of air and is a bit noisy. Great for a pi under full load, or you can connect the fans to 3.3v or use a resistor inline to slow them down. Not sure what that would do to the LED's though.
All parts printed on normal settings with 22% infill except the power button and the feet that were 100% infill.
Supports were needed. I'm sure you can figure out where they need to be,
The case is designed to glue together all five sections. [ case_top.stl, case_bottom.stl, case_front.stl, case_back.stl, and PSU_Cover_Side.stl] Use superglue or CA Glue.
In closing
This case took to much time to make and went through a lot of design changes but was super fun to make. I hope you like it.
Questions welcome.
