I'm a huge fan of the Spiral Chess set by CdR but I printed this for a classroom and I wanted to include magnets in the bases. The pieces themselves already worked great for fitting a 10mm magnet in the base but I didn't like that you could see the magnet. And there wasn't a good way to glue it in without seeing all the glue too.
This remix closes the top of the opening, but leaves the bottom open so you can insert a magnet. I used 10x2mm.
This remix includes the original style of knight that came with CdR's set but I also remixed the knight to look more like a traditional horse. You can find that here.
I also remixed the chess board I printed to include a spot for magnets in the board.
The author remixed this model.
