Tape-on Wall Hook

This utility hook attaches to the wall using 36mm (1.41") painter's tape and removes cleanly, sort of like a DIY command strip. To install, feed the tape behind the vertical column and in front of the diamond sides. The long tail at the bottom helps direct torque into the wall instead of the tape. The weight limit is around 200 grams. I tested a 5 meter / 220 gram string of 50 LED mini lights on a single hook, and noticed the tape gradually unpeeling from the wall before falling off around the 26 hour mark. Lighter loads should last longer, but I would not recommend using this for anything fragile.

I've also added a simpler Y-shaped hook for 19mm (3/4") Wall-Safe scotch tape. I didn't test its weight limit, but it works fine for icicle lights with 700mm hook spacing.

Printed with 0.2mm layer height, 2 walls, and 10% infill, around 1.3 grams per hook. There's not much point printing it stronger, because the tape adhesive tends to be the weakest link.
