FRC Hatch Grabber Remix

thingiverse

Some STL files got scrambled, so if they're scaled to a tiny size, bump them up to 2540%. When printing the hatch plate #2, make sure to add supports to the overhang on the side with the fillet. For the hatch support #2, add supports to the overhang as well. Use a 3-inch stroke piston when printing. The mounting hole has a countersink for a 1-inch washer. The plate features four countersunk holes for 1/4-inch rivets and a center hole that fits a 3/16-inch rivet. A 1/16-inch piece of aluminum is sandwiched between the frame and plate, which are mounted perpendicular to each other with the plate standing upright. The frame is attached using 1/4-20 bolts instead of rivets since they tend to break the part. The frame itself prints on its side, as do the arms, with supports in place.
