This is a MINOR change to timbologist's excellent work
Some folks were having difficulty with gluing the 2 halves together so I mashed them into one model and added an oil hole for good measure.
I've included the gear and dial from the original model.
Print it upright with the large (gear) end down with supports. As with the original you'll have to drill/ream the holes to final dimension and tap the set/grub screw holes.
