Backpack Hanger for Double Sided Tape

A simple backpack hanger that can be attached to surfaces suitable for double sided tape. I recommend printing it on the Textured PEI Plate so the tape has more surface area to stick to. You can print it in PETG for added strength, but my own models are printed in PLA since the backpacks aren't heavy. There are three plates with three different depths, 30mm, 35mm and 45mm.
