About this model

Remixed bolt sorter to accommodate hex nuts rather than brass inserts. If the nuts don't fit snugly, add some glue or scale the holes. Three separate STLs are available for MMU printing, one for the base object, one for the tick marks, one for the lettering/numbers. Printed on Prusa MK3s MMU2, 0.15mm layer height. Any infill % or outline number should be fine. Blender file is partially cleaned up from imported STL of original design. TODO: embed magnets for table adhesion as well as keeping the screw in place for length measurement.
