Derived from
MK5 Wade's-Style Tensioner
by ScribbleJ
Description
I made a derivative because I wanted a single object that would allow direct drive of both DC and stepper motors, offset steppers using Ruttmeister's gears thingiverse.com/thing:5795 and incorporate ScribbleJ's tensioner!
Instructions
thingiverse.com/thing:6402
thingiverse.com/thing:5795
The above links contain instructions on assembly and required components.
I have not made this part yet as I'm running very low on ABS. However I've sliced it up in SF and the mesh has no errors and looks fine.
Lenbok suggested adding a cleaning portal to get to the filament drive gear so it could be flossed without needing to take the tensioner off, which is the only modification in the second file. If there are any glaring errors let me know and I'll tweak the file.

Printed the part myself at last, with the extra bolts I had on the HBP it's a REAL tight fit, had to do this raftless without even an outline.

Printing, but don't have any spare steppers to run this off of yet.

Ive always wandered about printed extruder parts... do they not warp with the constant heat coming from below?

I just printed Ruttmeister's 51-tooth and 14-tooth NEMA 17 gears, plus most of the
âcleanerâ adapter plate, planning to glue on the remaining ~3cm later. I have two problems with the plate. One is that there's no hole to accommodate a nut or bolt head on the plate side of the tensioner (image attached). I'm not sure how I'm supposed to keep the M8 bolt in there. The other is t
hat the slots for the stepper motor are ~3mm too short to accommodate the 50mm axis-axis spacing of the gears when using the 14-tooth version of the smaller gear.
When I made ScribbleJ's I used some M8 pan head style hex bit screws I picked up at Ace. They have a much smaller head than the socket style.
I can't file the slots out: they hit the hole. Fortunately, the hole is un-necessarily big for this set of parts. Ruttmeister's 51-tooth gear's shaft doesn't fit in the extruder hole. To mesh properly, the NEMA 17 gear fully clears its hole. So, the motor hole could be as small as the stepper's 5mm shaft. I think I might have to muck around in OpenSCAD, now. :)
ScribbleJ's original doesn't have room for the bolt, either. I've asked there how to hold it in.
