This is a checkerboard that I designed using tinkercad. The print is quite small and if you want a larger less potable print feel free to modify it, I will try to post some photos of the print later on. please notify me if you come across any flaws in the print. I only put in 12 pegs and you need 24 I did this so people without a double extruder can print in 2 colors
Good luck with this print
I used a software called tinkercad to design this print. tinkercad is a basic cad software great for any level of designer.
You will need a good detail 3d printer if you are printing it small and you will also need a good filament I personally recommended PLA
