Canon FL 58 & 135mm follow focus gear

cults3d

Canon FL 58mm f1.2 & 135mm f2.5 follow focus gears.. The print has castilations that mesh with the grip on the lens barrel. The one for 135/f2.5 also fits the Canonmatic R 100/f2. The gears may fit other lenses, but not the rubber grip FD ones. Printed in hard PLA the 135 was a tight fit on my lens, though careful not to scratch the paint finish while fitting.. Alternatively the print should still be secure in a softer material, SLS nylon or flexible PLA. The 58/f1.2 I've made slightly less tight (at least as a FDM-PLA print @ draft 0.2 in Cura). The gears are 114t x 0.8 pitch (which is the same as many Arri lens gears), approx 85mm dia. Gear thickness: 8, 12 & 22mm included. The diameter of the lens: 135/f2.5, focus barrel is 67.75mm. The 58/f1.2 is dia 64.8mm.
