Chess set

 Chess set with a foldable chessboard

Figures are made of two parts - body and head. Only the horse's head needs supports.

Update ! 

Added new horse head, better modeled, it's not perfect, but if you like it more, you can download it

I uploaded the g-code with my settings - variable layer height - for better printing of overhangs, finer details, 5 perimeters, 40% infill, 10 bottom layers - so that the figures are strong and have weight. also a horse head model with supports
If the models with a small surface would come off, especially the heads, use the outline around it.
The parts hold well even without gluing
Checkerboard - fold the frame and connect the squares, 32 of each color, the last one is the most difficult, but I succeeded. The outer dimensions of the checkerboard are 35,3 x 35,3cm, The size of one playing square is 40x40mm

You can make your own size, just increase the parts by the same percentage in all directions
