M6 PTFE Coupler Joiner

prusaprinters

Wanting to print at higher temperatures on my 3D printers, I had a need for this and didn't see anything readily available.  Fusion 360 to the rescue!!!Due to the global supply chain making everything ridiculously expensive, I designed this M6 coupler so that I can use both the stock PTFE tubing that came with my Ender 3 (or any printer for that matter) alongside a length of Capricorn tubing into the hotend.The joiner is shallow enough to allow one M6 coupler to “bottom out” on the joiner when screwing it in.  The other M6 coupler screws into the joiner to the point where it “butt ends” itself up against the other coupler, creating a tight, uninterrupted filament path.I've been using it for several months now with ZERO issues.  Hopefully you'll find it as useful as I have. :)
