Accessory holder for NanoQuad quadcopter as can be bought on flyduino.net. I use it to hold my receiver and a bluetooth communication module. This way their mass stays close to the center of gravity of the drone. I designed the part in tinkercad. It can be found here: https://tinkercad.com/things/bePNAASvfCrIt should be easy to print. I did it without supports and 0.2mm layers, in PLA and with 40% infill.
