I needed some hook holder place for my helmet :)
Inspired by tornadex (https://www.thingiverse.com/tornadex) but his design uses 2 faced tape, i personally don't thrust tapes >_<
Jup my print was rushed, i was impatient :D
Please dont print version3 or if you do print it with high infill !
Same goes for version4 print it with high infill, it is more stable but better safe than sorry.
Holding screw holes need to be 50mm apart, and preferably screw heads not bigger than 9mm
