the board has a sise of 20 x 20 cm and is very useful when you're on the go.

Instructions:

• print the file using flex filament (I'm using TPU btw, but even more flexible filament could be better). TO OBTAIN BEST RESULTS WITH FLEX, PRINT IT SLOWLY
• cut out a peace of tissu slightly larger than the board and apply the printed board on it. Please refer tho those instructions at 2:18 : 

• use scissors or a cutter to remove the leftover tissu. make sure to not cut into the printed surface.
• for the peaces, i've simply used some cheap small ones. You can also find some to 3d print (just print them small).
