Bauhaus Chess Set

Bauhaus chess set, designed by Josef Hartwig in 1923. The idea behind these pieces was that the design itself reveals the way that the chess piece is allowed to move - thus the L-shaped knights, etc.

These chess pieces can also be used to calibrate 3D printers, as most of the pieces are simple cubes. All of the pieces, including the board square, have negative areas cut out from the bottom to accommodate 12x3mm round magnets or weights. You'll have to adjust the orientation in your slicer for best results.

Update: added an alternative knight (knight_02) that does not have the magnetic base, but is more in keeping with the original design - I noticed on another reference site that the knight actually is designed to be L-shaped on all 6-sides. Unfortunately, that won't work with a center magnet in the base, but it is a more robust design - so it may be worth living without magnetic knights. :)

Update: I decided to create a set of pieces without the cut-outs for magnets. These
