MT Center gauge (center finder)

thingiverse

Center finder inspired form Woodpeckers MT Center Gauge. See also the bigger version: MTXL Center Gauge. I designed some gauge bars in metric and imperial sizes, ask if you want some other sizes. Imperial: 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1 inch. Metric: 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25mm. You need: 2 x Bottom.stl 2 x Top.stl 4 x Pin 2 x Thumb_screw.stl (choose the small or big model) Gauge bars that you want! 2 x M4x16mm hex bolts for thumb screws 2 x M4 nuts by gauge bar Updates 2016-10-19: Added 2 new thumbscrew designs 2016-10-21: Remove old thumbscrews and adjust diameter of new ones, they were too big Post-Printing Accuracy To get best accuracy possible, the fittings are tight. It could need a little sanding for perfect fit, particularly the "bottom" holes, and the "top" hole in middle, where thumb screw goes. Don't sand two other holes in "top" part, they are for pins and have to be very tight to keep assembly.
