When I got for climbing or do stuff in my workshop, I remove my watch and just throw it in my backpack or put it in my pocket. To make sure it doesn't get all messed up and scratched I designed this little protection case.
Designed for two 5x5x5mm cube magnets.
I printed it with Prusament PETG and just pushed the magnets in. Before pushing them in make sure they are oriented the right way ;-).
