Flywing 450L V3 Battery Tray

Flywing makes amazing RC model helicopters that utilize GPS and other forms of stabilization.  In my case I purchased a FW450L V3.  A battery tray is an inexpensive part, but it is necessary to hold a battery pack inside the model.  One tray comes with the model, but I wanted to have two more packs ready to go when I fly without dismounting and mounting the packs to the same battery tray.  So I designed a battery tray for 3D printing.  I also made the tray bottom 1mm thicker so that the pack would clear the main gear and one-way bearing. There is a slot for two-sided velro to hold the battery pack in place.

I sliced in PS 2.7.4 and printed the tray with Prusament PETG (always very slowly) with supports on build plate only and 0.2mm layer height,  40% gyroid infill.  Used stock Prusament settings on a MK3S+ with Revo 6.  Supports break free cleanly.
