About this 3D model

Center finder inspired form Woodpeckers MT 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" Metric : 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 25mm You need : 2x Bottom.stl 2x Top.stl 4x Pin 2x Thumb_screw.stl (choose the small or the big model) Gauge bars that you want ! 2x M4x16mm hex bolts for the thumb screws 2x M4 nuts by gauge bar Accuracy To get best accuracy as possible, the fittings are tight, it could need a little sanding for a perfect fit, particulary the 'bottom' holes, and the 'top' hole in the middle, where the thumb screw goes. Don't sand the two other holes in the 'top' part, they are for the pins and have to be very tight to keep the assembly. The nuts may need to be pushed in the bars with a small hammer or something like that.
