Was trying to find a good way to hang up my wreath on my door this Christmas without having to drive a nail into the door and thus damage it. This design works such that the weight of the wreath itself pulling down forces the clamp to better its grip on the door :) The door in question is a standard European door with a rear lip of 20mm.

The holder was printed on a Prusa in an enclosure using ABS, however, I don't see any reason as to why PLA wouldn't work either so..... Happy printing and merry christmas to all!!
