Filament drive pulleys

It’s been a while since I last posted something, not that I haven’t done anything, but not something big enough to tell about. 🙂

But today I got something to tell about! I made a bunch of filament drive pulleys, they are the same size as the ones makerbot sells, except mine got 5 and 8mm holes, so they can be used on all nema17 motors, and the 8mm will fit the ones with a planetary gearbox on.

So yeah.. Awesome…….. WAIT! It gets better!

I also made a little video of the process from the cnc lathe making the blank pulley, followed with me making the hobbing on a manual lathe. Enjoy! 🙂
