A 3D printed part for our FTC robotics teams 19589 and 22347 from Ridgeline HS in Liberty Lake, WA.  The 4mm holes are on 16mm centers in X and 32mm centers in Y, compatible with the GoBilda hole pattern / system.  Print either face up or face down for your preference.  I suggest printing yellow first and black last.  We've printed this a number of times successfully… can't find a super clear image of it, but it's on the robot in one of these photos.
