Update2: Rotating it back to the original design will yield a stronger print for hobbing. Update: Rotated to avoid long bridges. Default parameters: //Parameters bolt_bearing_diameter = 22.0; bolt_bearing_thickness = 7.0; bolt_diameter = 8.0; bolt_offset = 22.0; bolt_wall = 2.0; bolt_drill_tolerance = 0.4; tap_diameter = 6.0; tap_offset = 18.0; tap_bearing_diameter = 19.0; tap_bearing_thickness = 12.0; //dual bearings for extra alignment strength tap_wall = 4.0; tap_drill_tolerance = 0.4; cut_depth = 0.7; Print multiple jigs with different cut depths. Default is 0.7. You might want to print out 0.9 and 1.2 and so on for deeper cuts. Default additional hardware: 2 x 608 Bearings for hobbed bolt 2 x 626 Bearings for tap (using 2 bearings while tapping for extra strength and proper alignment) 1 x M6 tap
