Print-in-Place Chinese Style Abacus (Suanpan)

This abacus (frame and beads) are all printed together in place.  Overall dimensions are: 186mm x 116mm x 10mm.

For a simple 2-color design, load the STL file and program a filament change to print the frame decorations and tops of the beads in a different color.  The basic frame is 6mm high, so program the color change above 6mm (6.2mm when using 0.2mm layer height).

If you have an MMU, you can go wild with different color beads and decorations.  After loading the STL file, split it into parts to get independent control of each element.  As a starting point, you can use the 3MF project file which is already split into parts with color assignments.

If you have not used an abacus before, there are many resources on-line; here is a good starting point:

2024-01-03 Update: Improved the model (“Abacus3.stl”) to provide additional clearance between the beads and frame, updated the description, added a full-color 3MF project and photos of a full-color print.

Miscellaneous Notes/Comments:

• Print using PLA with a 0.4mm nozzle and 0.2mm layer height.
• No supports are required.
