Summary

Designed in FreeCAD to fit a Hover X1 pro (folded) with its carry bag and 4 batteries secured in the lid.

There are a couple mm of wiggle room to fit the bag it comes with.

Designed this after seeing there was no case on the internet that seemed secure enough and water tight.

Latch x2

Printed in tpu:
Seal
The seal works best if you scale it down to about 98%.
Just place the seal on the slot and close the lid to seat it in place.

Hardware:
M4 30mm screws x6

Installation is simple, just screw them into the holes...
They should be a perfect fit. If not, time to tune your printer.
