this box was made for a tester, used for triggering the emergency receiver of a community gate system, for emergency vehicles.  thanks VERY MUCH for the fusion 360 file.  I customized the box to match the tester size.  i THEN added a hole in the front, and extended a protector, to protect the infrared transmitter bulb.  I THEN added holes that show the indicator light, and another hole ot insert a threaded 3d bolt, that screws down to hold the switch (a press switch) in the ON position.  I then made a pole threaded holder, epoxied it onto the case, and epoxied a 5-16 nut onto the case, and the threaded 3d bolt inserts into that. (2-part expxy works great).  Thanks VERY MUCH for this box design,it works great, latch is strong, and printed correcly on first try !  and the Fusion 360 file allowed me to easily do these modifications. !
