I was in need of an adaptor to clean my chandelier, top of door frames, etc. Then I've bought the super cheap (and small) Tinyboy 3D printer and this was one of my first projects. It is necessary to glue the parts together (I did using Loctite super glue) and also trim some small bits that are on the way.
I hope it will be useful to somebody else :D
