M5 Pivot Outside Transfer Calipers
A pair of 140 mm bowed outside transfer calipers that print already assembled. The legs turn on a 11 mm hollow printed pivot pin with 0.45 mm of clearance. An M5 bolt goes through the pin, with a 15 mm washer underneath and a nylock nut in a hex pocket on top, so you can set the drag. The jaws open to about 60 mm and let you take the OD of pipe, dowel or turned work across to a rule or calipers.
