Hello all you amazing and fellow sailrite clone enthusiasts. I’m super new to the 3d print game. I just got my first sailrite clone and I’m short on the cash but want a MONSTER wheel. I have a newbie question how my of the 3d files do I need to download? Which ones? I’m have mine done online at cloud craft. Also what are the units of measurements? MM, CM, INCHES? Thank you all for your contributions and amazing advice. Ohh imusig all oem parts so no servo, just a plain ol’ OEM 1.5 amp motor.
