i have a couple of more thoughts about the bevel gear stl output, 1. gears print best with the flatside down ,could the stl output be rotated around the x or y axis by 180 deg 2. the z axis 0 would be better at the bottom of the gear 3. the back of the gear would be better being completel
y flat 4. netfabb finds various errors with the stl files and cannot fix them without degrading the whole gear
there may be something there that can be fixed
i have found that i can erase the entire centre of the gear in googlr sketch , then add my own centre , rotate the lot then export it to slicr3 and get a decent prints with shaft holes too see pics
