Bowden Clamp for Rostock Hotend

Bowden Clamp for Rostock Hotend by jamesarm97 Aug 23, 2012

Description

This replaces the standard Rostock Bowden hotend mounting that used the M8 nut. I did not like the way it threaded on and would come loose. I modified this derivative from an Ultimaker bowden assembly and the original Rostock and this is what I ended up with. It works with a 4mm tube. The insert / collet could be a little tighter but I just used a piece of tape around the bottom of the tube.

side M4 nute???
The STL's posted work with 1.75 and the 4mm outer / 2mm inner diameter tubes. That is what I am using. I haven't regenerated the bowden_ring file yet. It will work if you put a wrap or two of tape around the tube first where they meet. The original is a little loose.

Instructions

Print bottom in ABS, 100% fill at .20-.25mm layers. Use ABS if possible to protect from the effects of heat.I printed the cap on my Rostock with PLA because I liked the look. Source files to come soon.

Any chance for a version for 1.75mm filament (2mm tube.) For some reason the scad files keeps crashing.

 Any way you could post SCAD files for people with different sized bowden cables?
Thanks for the good work. I used your design and scaled it down then used it directly on my Rostock's Steves HotEnd. An upgrade to my recent upgrade. I am still building the printer. Fun! See Thingiverse: 29141 :)
