I made these chess pieces for an automatic chess board I am working on. The hole on the bottom of the pieces is there to fit a magnet. 

• All pieces except for the horse can be printed without supports. 
• The kings star is a separate file so you do not need supports. 
• the pieces look fine when using the standard 0.4mm nozzle but for the best results i reccomend using 0.2mm

The files are 3mf. instead of the common STL. 3mf files are smaller and more accurate and still work with all slicers I've tried.
