Semi parametric (don't hate on me, still a beginner in Fusion :D) LiPo tray, designed and suitable for Sprektrum Smart 4S 3200mAh LiPo (see pictures). Should be pretty easy to adapt to different sizes as well.

I recomment printing on its side as in the 3MF to have suitable strength along the hooks.

The small clip is used to hold the tray in place and needs to be removed to be able to move the tray. The baseplate can be glued into the model.
