These are some of the custom parts I made to build my dual extruder RepRap Prusa variant. There are other parts used that were designed by other people. I will be compiling a complete list of the parts with links to them.

One thing for the geared axis drives I designed, they use the small gear from Greg's Wade's hinged extruder. So that would need to be downloaded off thingiverse.com.

I will be organizing this top post more as time goes on.

I added a new file to the list called Axis_pulley_4.12.12.c.zip. It is going to be for the new belt reduction axis drives. Still need to create brackets and stuff...

OK, so the pulley needs a little work. The tooth spacing is a little too short on the large part. Otherwise I think it's the coolest thing I've ever printed. Tongue

I added an updated file called Axis_pulley_4.14.12d.zip. I adjusted the diameter of the large pulley to be a better fit with XL belt teeth. I'll leave the 4.12.12c version up, just incase the large pulley will fit T5 belts. I haven't got any T5 belting to test with.

I learned it pays to make multible files while you work in Sketchup. Dodgy

I had this file corrupt on me twice already. That is why there are letter designations after each file date. Basically just restore points. Smile

Starting to get the belt drive axis concept down pat. Cool

I'm sure I'll have tons of clearence issues to fix once I print and get a belt. The motor is adjustable for belt tension. I still have to build the other brace.

Very cool Nate, I think you've got it.

I added the files for the latest Y axis belt drive. You will also need the Axis_pulley_4.14.12d files to print out the belt pulley. It has been working very nice on my prusa. Big Grin

Thanks Jeff,
I forgot to mention that the belt needed is a 12 inch outer circle, 60 tooth, 1/4" wide XL belt. Trade size is 120XL. I ordered this part # from McMasters 1679K24.
