Summary

These are lights I've designed and maybe you'll find them interesting too. These are designed to hide a power bank inside the frame of the bike. This makes it really neat and allows quite a large battery too. I'm also providing all of the STEP files for easier customizability. I've written instructions on how to build it here:
