Simple Matek (http://www.mateksys.com/?portfolio=m10-5883) GPS module holder for Flywoo Explorer drone. After printing needs a bit of filing in order to tightly fit GPS module also it is capable to secure GPS with included heat shrink film. Mine particular build is done from PC but any material could be used here. I see that holder conflicts with buzzer but with sliding a holder closer to top it's fine.
The author remixed this model.
