Rebreakable Karate Board

I've designed a rebreakable karate board to test your strength and how you compare to other people.

I've made 3 difficulties, an easy, medium and a hard board, from 10mm to 15mm thickness, the 10mm one is very easy and is mainly designed for children, the 12mm and the 15mm ones are quite more difficult and require a lot more effort than the easy board, please note that the strength needed to break these boards are not the same as proper karate boards on the market.

The test prints sounds like what its supposed to do, to test if it fits/works or not, these are printed with quite a bit of tolerance, the same as the boards itself ,so if your prints don't function as intended, then there is something wrong with your printer, you can also use the test prints as fidget toys and can be very satisfying to snap.

Please print the boards the intended orientation since this is the strongest orientation and also so that the boards fit together properly, and also enable brim since you would
