It is very important to be careful assembling this case. Since it is really slim you can find yourself in trouble fitting the BBB inside the case. My recommendation is to insert first the usb side and after the HDMI side, deforming the HDMI wall to prevent damage your connectors. I will not assume any responsibility if you damage your BBB.
This is a Beagle Bone Black Wireless case based on this model https://www.thingiverse.com/thing:471661I had to implemented from the scratch since the original model was on SCAD and I am not familiar with it but I used his measures.
Several modifications has been done adapt it to the Wireless version and to improve things: buttons, serial, screws, pockets for two SMA antennas, etc
