M10 toilet seat fastening wingnut

thingiverse

The old nuts attached to the bolts for my toilet seat snapped, so I printed several test models before coming up with this version that fits perfectly, which suggests they could also work for others. Customized version of http://www.thingiverse.com/thing:193647 Instructions To print the following settings: type = nut thread_step = 2 nut_height = 6 thickness = 2 step_shape_degrees = 45 outer_diameter = 14 wing_ratio = 1 inner_diameter = 8 drive_diameter = 5 head_type = hex facets = 6 nut_diameter = 13 head_diameter = 12 nut_resolution = 0.5 thread_length = 25 thread_outer_diameter = 8 drive_type = socket texture = exclude nut_type = wingnut nut_thread_step = 2 nut_step_shape_degrees = 45 non_thread_diameter = 0 resolution = 0.5 countersink = 2 slot_width = 1 nut_thread_outer_diameter = 10 non_thread_length = 0 slot_depth = 2 head_height = 5 Using Simplify3D to print these, I used the following settings with PLA: first two layers at 0.2mm layer height, 60mm/s, 30% infill, 4 top and bottom layers, 2 shells. remaining layers at 0.1mm layer height 80mm/s, 30% infill, 8 top and bottom layers, 2 shells.
