Updated 07272018: Version 3 with larger hook

this is a snap on two pieces wall hook inspired by 3M command hook however following a no-support design. This one is designed to use with a 3M stick strip which can be bought separately. For those who likes the 3M stick strip (very useful for many purposes) but don't want to buy the hooks, this is the hook you will like.

My design solves the problem by hiding the strip beneath the hook entirely. The design include two parts: the wall part which is supposed to stick the strip and the hook part which fits into the wall part. I use white PLA. Print the hook part flat and wall part on its side.
