Proportional Dividers

thingiverse

These can be useful but I feel they could be improved. Good for artists transferring dimensions into a small picture. No good for scribing lines! The washer and bolt have to be printed with 100% infill. The idea is that the pivot can slide anywhere in the slot, or it can be turned 90 degrees and then fit into set positions. The ones that are very close to each other don't work well in my prints - and those are around pi and pi/2 :( I think it would be best to do away with one of the cutouts.
