Print-in-place planetary gear maker
A gear set that comes off the bed already assembled.
About the print-in-place planetary gear maker
A herringbone planetary gear set that prints as one piece and turns straight off the bed. A classic desk toy and a good printer test.
- Herringbone teeth hold the gears in, so nothing falls out.
- If it prints fused, raise the play between teeth to 0.3 mm or more.
- Turn the sun with a hex key through its hex hole.
