Suanpan Abacus

thingiverse

A basic suanpan abacus made as part of a history of computing project I'm working on. I should have made the beads bigger and the overall height shorter, but I think it printed good enough to play around with an abacus for an afternoon. **Parts to print:** - 1 x frame-middle.stl - 2 x frame-right.stl - 2 x frame-top.stl - 9 x rod-1.stl - 63 x bead-1-1.stl **Hardware required:** - 4 M3 nuts (captive nut inserts) - 4 M3x12 low profile hex bolts
