Print-In-Place Hinged Pinch Collar For 3/4 in EMT
A clamshell stop collar for 3/4 in EMT conduit (23.4 mm OD) that prints in one piece with its 5 mm hinge pin already in place. It swings open so you can snap it on partway along a rail, then one M5 bolt and a captive M5 nut pull the 2 mm pinch gap closed. You don't have to slide anything over the pipe end. It is 16 mm tall with a 37 mm OD body, has a 23.6 mm bore and is 56 mm long overall. Use it as a height stop, a rail end-stop or an anchor point on EMT.
Rod-Clamp Station Pointer Collar
This part is for the 'NEMA17 Geneva Indexing Turntable' kit. The collar clamps to the top of the fixed 8 mm rod through an 8.3 mm bore, with an M3 set screw and a captured M3 nut. Its OD 11.4 × 4.5 mm pad holds the upper 608 bearing's inner race in place. The collar is 22 mm across and 14.5 mm tall. A 60 mm pointer arm ends in a 60° arrow that sits over the platter's r = 50 mm stations.
Elbow Axle Thrust Collar
A shaft collar for the 8 mm elbow rod in the 'NEMA17 Belt-Drive SCARA Drawing Arm' kit: 32 mm OD, 10 mm tall, with an 8.3 mm bore and a raised thrust ring (11 mm OD, 0.5 mm tall). The ring pushes up only on the inner race of the forearm's lower 608 bearing. It locks with one M3 set screw into an M3 nut that drops into a 5.7 mm slot open at the top. Two grip flats 29 mm apart let you hold it while you tighten.
