Twin-Detent Drawer Runner
Part of the '2020 Gridfinity Drawer Tower' kit. This 135 x 20 x 16 mm side rail bolts to the inner slots of a front and a back 2020 post with two M5x10 socket-head screws and drop-in T-nuts. The 5.5 mm holes sit 115 mm apart and have 10 x 5.5 mm counterbores, so the heads end up below the face. A 6 x 5 mm ledge carries one side of a Gridfinity tray. Two 0.8 mm half-round ridges click into the tray's notches. The ledge ends have 1.5 mm lead-in chamfers. The part is symmetric, so all 8 runners are identical.
