M3 thumb wheel / knob / screw / Wing Nut

thingiverse

Works with an M3 hex nut. I printed mine at 0.4mm layer height. I used a rubber hammer to pound the hex nut in place. Make sure to put a screw through on the nut's side first at least to thread the plastic. Instructions Using the following options: wing_thin_d = 4 thread_d = 3 roundness_ratio = 30 wing_count = 5 nut_th = 2.3 nut_d = 6.2 hex_nut = 1 wing_h = 3 wing_thick_d = 3 total_d = 25 nut_shoulder_x = 2.8 nut_shoulder_z = 4
