I was browsing Thingiverse for S500 quadcopter things and stumbled on the Naza GPS and LED holder by user mowbs. I printed his file, but when I tried to fit my Naza GPS puck, the holder was too small for the puck. I created just the holder part with the dimensions to fit my Naza GPS and a generic GPS puck that was in a F450 kit I purchased from Amazon.

The countersink hole is about 1mm too short for the M3 socket head screws to be flush with the bottom of the holder. I used a 5mm drill bit to deepen the countersink on my holders. The screw hole pattern matches the rail arms of the mount that mowbs created.

The holders were printed on a Polyprinter 229 at my local library.
