##updated 8/19: Fixed manifold, uploaded B(ack) and F(ront) versions of the file for those who aren't comfortable mirroring in software. Updated 8/12: Modified Tension arm and an even more vented/slimmed housing model, with additional support around the tension bolt-hole, are now available. For my first big print, I made Markqv's replacement extruder, which worked so much better than the stock one. Then I found the "v8" and the 3Up housing, each of which addressed some of the issues I had with Markqv's design. The Two Up is shipping a "V2" design that uses completely different extruder tension springs and hardware. The MarkQv, v8, and 3Up use old v1 springs and hardware. So I bring you HooptieJ's Two UP extruder carriage. I liked the venting on the 3up because it gave me visibility into my print and helped with heat creep issues I had with Markqv. However, the 3up's wiper box wasn't something I was interested in, and the tension arm angle from the v8 didn't work for my fan mounting. Based heavily on Marqvs' extruder, I added some vent windows to the top and left side of the carriage and moved the bolt bracing the tension arm. I also removed some unnecessary case material. Using all original hardware from the V2 kit, no extra bolts or screws or springs are needed. Enjoy!

Updated 8/19: Modified Tension arm and an even more vented/slimmed housing model with additional support around the tension bolt-hole have been added to the design.
