Compact Belt Rack / Hanger

I wanted a space efficient/relatively organized way to hang up belts, so created this tree-style rack. 2 configurations - either 8 slots in a flat/narrow rack, or 12 slots using all 4 sides.

Side A, Side B, and the spacer are required
Choose either the universal hanger for normal size closet rods, or the compact hanger to save more space if you have a wire-style rack.
Print Aux A and Aux B to add the face hangers.
Parts are held together with 4x M3*25 mm screws and hex bolts (I used cap head but shouldn't matter).
