I created a small holder to keep my Matek USB-C/Buzzer extension board in my plane.
Printed in PLA holds the board by some friction and uses the two holes in the board itself. Allows to plug USB-C directly but also the board can be easily removed if more flexibility is needed.
Bottom pattern is 20x20, in my case I had four screw threads sticking out of bottom of plate on a plane so I just used some E6000 to glue the adapter's legs onto them.
Printed in PLA, .25 layer height, no supports needed.
