Makergear Filament drive goes Bowden by Luke321 Mar 19, 2013

Description

You can use the Bowden Connector part to convert an existing makergear filament for Bowden use with a pneufit.

Or print the modified Filament Drive which already accepts a pneufit.

The Space is for the Ball Bearing!

Would you please correct the part number of the spur gear in the instructions.
The spur gear from SDP/SI model is incorrect!
This is the right model: S10T05M022S0508
No problems at all, straighten out the first few centimeters of the filament and it goes trough without a problem.

Thanks for this -- I'm considering it for my Rostock mini as well. Do you have any problems changing filament with this design due to the lack of a fully hinged idler?
No problems at all, straighten out the first few centimeters of the filament and it goes trough without a problem.
If you don't mind, could you add information for the pneufit and bowden tube?
I updated the list forgot some things :)
