NOTE: I have updated this model to accommodate the use of gutters on the board. This board upgrade allows for the legs to attach to the board via magnets! It uses 2x3mm (really 1.7x2.9) magnets, I purchased mine from Amazon. Be warned that your magnets may not fit exactly the same, I had to tune this for mine. Depending on your printing tolerances, you may need super glue to keep the magnets in (I suggest doing this anyways to avoid losing magnets). To get a full board, you must print these along with the end zones, on ramps, and feet (integrated version) Purchase link: https://www.amazon.com/dp/B09NRH97D9
