Strap keeper for Whoop strap v3

cults3d

I've got a Whoop strap fitness tracker that doesn't come with a strap keeper, causing the lower part of the strap to stick out when I wear it, driving me crazy so I designed and built a strap keeper. Optimized for printing on an FDM printer with a 0.4mm nozzle which should result in two walls that fit snugly onto the strap without sliding around. It can be printed in flexible filament but I find that printing in PETG produces no noticeable results, making flex filament not absolutely necessary. Fusion 360 files are available upon request if you need them, but if you're struggling to model something as simple as this from scratch then it's unlikely you'll be able to modify it successfully.
