Quest 3 controller holder for bag

I wanted a Quest 3 controller holder that stops them from rattling in a bag and expending their battery, but could not find one on Thingiverse. I found a controller model however.

I figured I should make a basic version of it for myself, so opened up OpenScad to create this design. It is still pretty much the starter version since I didnt smoothen the sharp corners yet.

Just mirror it while printing for the other controller.

UPDATE:
Smoothened out the corners, and made a cutout to make inserting and removing the controller easier.
