A fully printable and easy to assemble split-flap counter.
Print Settings
Supports: No
Infill: 10
Notes:
No support is required.
I printed the parts with 2 perimeters, 10% rectilinear infill and 0.2mm layer height.
I recommend splitting the flaps.stl in PrusaSlicer to fit smaller build plates.
Right-click the object -> Split -> To Objects.
Add a color change for the first and last layer when printing the flaps.
