Cotton Reel Holder

The second prototype of a cotton reel holder. This item is designed to be mounted on a wall or board with M3 (or nearest) sized screws.
Holds 4 reels per panel. The prongs are tilted to 15º. If you need more than four reels, print duplicates and tessellate.
Sized at 120mm per side. Fits nicely on a Replicator 1. Printing the first one now at 50% infill (overkill, but the prongs are in the wrong orientation to get much strength without the extra plastic). No signs of lifting so far.
