I've teste this model on most desks and tables and it has worked quite well, as long as the hanging surface isn't too thick it'll work just fine, I plan on making a second version with more tools attached: keychain friendly, bottle opener, among others.
Stay tuned for more updates!

Print settings:

• 4 walls thick

• 4 top and bottom layers

• 20% dense  gyroid infill

• 200µ or 150µ thick layers (best results with 150µ)

Gimme some feedback, I need that to improve on the next design
