Here's a Mario Bros. themed tic-tac-toe game! The playing pieces are mushroom power ups, with both bordered and borderless variants to match your preference. Borderless pieces can be seen in the first picture, and the bordered version is in the second. A pocket in the back seats a 10mm diameter, 1mm thick circular neo magnet; if magnets you have on hand are slightly different in size and shape the Solidworks part file included may be of use.
This project was designed for use with the Prusa MMU3. If you have the device already set up, then the .3mf files have already been painted, split onto platters, and are ready to go!
The print in the second image was made using Inland PLA filament in Black, White, Red, and Sand using the MK4 MMU3 0.40 nozzle 0.20mm STRUCTURAL preset.
The author marked this model as their own original creation.
