The BOXX Atom 4th Gen Transmitters and Receivers have a channel selection button and on/off switch that are really easily toggled/pressed.
I've designed these “protectors” that makes it harder for these accidents to happen. It still allows for the use of the switch and buttons but requires more effort.
Print in PLA. Mount using thin double sided tape. You will need a small craft knife to cut the holes.
The design is such to provide more surface area for the double sided tape to adhere to.
If you want a more permanent solution, you can glue it on.
The author marked this model as their own original creation.
