After designing and printing chess board and backgammon board tops for stagetop I needed some pieces and using the fusion 360 for 3d printing courses I had taken set off to make a nice stacking, no support, multi-color (optional) set of pieces using parametric modeling.

The 3mf is a complete set of multi-color pieces as created in bambu studio.  I don't know it's compatibility with other slicers. 

The step file is a single set (1 of each piece) multi-color from which I built the 3mf file.

The stl files are good for single color printing as the debossing of the symbol if very visible and easily painted should you want to do that.

stacks with just a little bit of clearance, optimized for bridging on the underside.
