Simple Pi 3/3+/4 compact holder/base

A simple holder that holds your pi.
Needs 4 m2.5 or m2 screws to hold the pi to it.
Should work with Pi 3 or 3+ because it has the same mounting holes.
I've only tested it with the pi 4b because I only have that pi.
See print settings if you want the triangle pattern on the bottom.
I put some rubber feet on mine to make it less slippery.
If this does not work with pi 3 or 3+ please tell me so I can improve the design.

Notes:

Turn top and bottom shells off and choose a 2d infill. I used trangle infill in cura. You can use any infill pattern you want.
More infill density=More solid bottom

Less infill density=Less solid bottom
