Date: 4th of August, 2013 Check out the freshly revised design for the MK7 filament guide! It's available at http://www.thingiverse.com/thing:127699. Wishing you a Merry Christmas and a Happy New Year from U-Design! Ho, Ho, Ho! This update is inspired by Yru's extruder (yegahC), but it has been completely rebuilt with a flexible integrated idler for easy maintenance, high precision, and ease of printing (just one module body and idler). It also caters to Twins (dual extruder) setups. It is compatible with the J-Head mount system as well. Looking for a top-notch Bowden extruder? Check out Bowden YRUDS, available for download! For those using a BiBONE 3D printer, we've got two extruders ready for you to click and enjoy at http://www.thingiverse.com/thing:21178. Interested in learning more about yegahC?

For the mechanical parts, you will need a large gear (56 tooth HTD3M), a small gear (15-16 tooth HTD3M), a 65 tooth, 4 mm wide belt (HTD3M), two 686RS ball bearings, one 626RS ball bearing, a hobbed bolt (M6x50 allen bolt), an M6x30, an M4x40, a spring, and a Nema17 stepper with a 25mm shaft. You can cut the bolt yourself by following the photo's simple cuts on the M6 Head. The design is suitable for 3mm filament. Want to generate pulleys?
