Nimble V1 NeoBreech Assembly Tutorial

Apologies for the trash autofocus! Still not used to shooting this sort of video. This is how to assemble my "NeoBreech" printable replacement breech for the Zesty V1 (or V1.2 shown here) Nimble Remote Drive Extruder. This design is new and may see changes driven by testing feedback. Please see the Printables listing for the latest parts, notes, and BOM information: www.printables.com/model/6260...

I'd be interested to learn more about this. Is your thesis published anywhere?

[@jamespray]

If I somehow gave the impression I've authored a 3D printing-related thesis, I'm sorry for the confusion, but my only thesis was a novel written for my MFA in Creative Writing, not currently published. All additional info on this design can be found at the printables link in the description.

will this fix the ripples in the nimble prints? I have a V2 with that issue, though i know this mod wont fit it im still curious

[@jamespray]

In my experience, the ripple is a combination of (at minimum) periodicity in the flex cable and eccentricity in the sintered (not machined!) hobs. This mod can help slightly with the first issue, because it reduces the insane bite strength of the original breech and therefore reduces the torque required to extrude, which helps flex drive accuracy. However, there's really no solving the ripple completely -- even with a hard shaft drive (which I have tried), the hob still causes artifacting on its own.
