About this 3D model
This is a watch band holder I made to... hold my watch bands. There are 9 slots for bands to go in, each with a width of 8mm. Most of my bands are the nylon velcro type seen in the picture, 8mm spacing allows them to be slightly squished so they don't slide out. I've included the .step file if you'd like to make modifications in your CAD software of choice. Made with Shapr3D (my first printed design from it)
