#####Difficulty
- Advanced
- I suggest that you try printing one of my other more recent gearsets before attempting to print this one because of the fact that it takes nearly a full spool of plastic to complete. If you have good luck and all the clearances seem right on a smaller gearbox of mine it's more likely that you will not have to print this one twice.
#####Scaling
- Do not try to make this gearbox smaller unless your using a really tiny nozzle (and super accurate printer) or SLA, the size of the gear teeth on ring gear #2 is already the limiting factor for how much torque it can handle, and if it was much smaller, an FDM printer would not be able to print them decently.
#####Torque Capabilities
6/11/17- Tested at 57LB-FT (some might call em foot pounds) which was 300LBS @2.28" off center with 300LBS of weight on the output, it held up really well, still no sign of failure except I accidentally broke my special tool, but that can be replaced with a socket. More testing to come.
####How This Works
- If you're using the included mounting apparatus, and mounting the gearbox with a rod through the 7/8" holes in the mounts, then rings #1 and #3 will be held stationary, and ring #2 will be the output.
- If you were to design a custom mount for this and it held Ring gear #2 stationary,…
