Been looking at the Alternative UM2 Feeder V6 over at https://www.youmagine.com/designs/alternative-um2-feeder-version-two and I had some ideas for improvements: 1) It broke apart at the thin parts around the inlet. (I don't know what the different versions of the body are for?) 2) I wanted to be able to use bowden clamps at both inlet and outlet 3) I wanted to be able to take my Bowden-tube right up to the gear. 4) The parts meant to break away was fused rather tightly to the finished part. I remixed the Extruder body and "solved" the above points. I maintained the mounting mount-ridges for the "Snap on Guide" - While the snap on guide doesn't match dimensions here, as mine has farther between the mount points - it does make for possibe future additions. Set as "Work in progress" as I might make minor changes.Print it with 100% infill. It works very well with 0.2 layer height. I see no reason for lower layer height, as it will only make for weaker part. I printed with ABS at 240c
