Easy to dis/mount RPI as snap hooks are fixed to flexible bars. Also made 2 hooks on one side to accomodate microSD.
To use with DIN912 M3 allen bolt hex socket head cap screws.
Near countersink fully hides head AND flat.
I used ABS, but any filament will go.
0.4 nozzle / 250/110 temp, no fan
4 top/bottom layers, brim 4 lines, 100% infill (less has no meaning and actually doesn't significantly decrease printing time due to slots)
0.2 layer height + adaptive layers @ 0.15 mm variation / 0.04 step
+ draft shield
