Simple Case i designed for the HB-RF-USB-2 PCB of Alex Reinert together with the ELV RPI-RF-MOD module.
Case has a 7mm hole for an external antenna and a snap fit top.
Tolerances are quite tight so make sure your printer is well calibrated.
Printed it myself with 0.2mm Layer height and 20% infill with black and orange Basicfil PLA (ran out of black after printing the bottom)
Print took about 2.5h for the bottom and 1.5h for the top on my Ender 3.
0.2mm Layer hight
20% infill
