Release just dropped for a #3dprinting upgrade I've been watching! https://www.printables.com/model/1110589-kevlar-bowden-sheath-system-instant-print-quality
Not a fan of bowden, but if you're doing bowden you want this.
@dalias That was a _very_ interesting read. My experience operating a Bowden printer definitely lines up with what is described there, and the solution is really clever.
@koz There's also Nitram's Stiff Bowden that predates this by quite a bit, but its only documentation is a video. https://youtu.be/cF33iXlFqVs
