LEGO mosaic compatable wall hanger

This wall hook is compatible with piece 67139 which is used as a hanger bracket by LEGO's line of dot mosaic art sets.

Hanger Hook

I printed these standing up on their bottom end with a raft just to be on the safe side. 

This hanger accommodates medium sized command strips (19 x 52.4mm / ¾ x 2in)

Spacer Version

This version lets you slot two hooks onto a connecting beam into a single pre-spaced assembly. This is what I have opted to use for my 4 prints as it made spacing out and leveling my frames a lot easier than trying to independently place 8 hooks. 

I do not know how this spacer would work with the world map set, but should be compatible with any 3 tile (48 stud) wide sets by placing the hanging brackets in slightly from the corners. (see attached image) The spacer will print just fine at a 45 degree angle on a Prusa MINI.

I applied a thin layer of super glue and let the puzzle piece connections dry before attaching the command strips.
