Description

Updates

Version 2.1 (09/27/23)

Added lead-ins to the filament entry cavity
Changed PTFE stop ledge angle at filament exit end
Added note about countersinking PTFE that enters the printer
Updated printing profiles
Added additional sources for the release rings so they can be purchased outside of the US

Version 2

Added through hole for an M3x20mm mounting screw. Printed with a 0.4mm nozzle at 0.10mm layer height
Added printable locking clip STL file to eliminate backlash in fitting/PTFE tube when pulled on
Print with single inlet side on the build plate. Add a 10mm brim to stabilize the print

Version 1

Background

This allows you to run material from the AMS or external spool without having to disconnect the PTFE tubing.

This uses push to connect fittings as you would see in a typical PTFE connector.

Release Rings: QTY: 3 of PC4-UM2

I do NOT recommend the printed release rings as they are too fragile and do not securely hold the PTFE tube into place.

Installation

Push the retaining ring into each end. After you insert the PTFE tubing until it bottoms out, pull back so the release ring has a gap between it and the printed surface. Insert the locking clip into this gap and then push the PTFE back in so it seats. This removes any backlash so the end of the PTFE tube remains firmly in contact with the bottom of the bore.

While not always required, I found it helps to countersink the PTFE tube entering the printer as it provides a lead-in to prevent snags.

You also need to ensure the printer buffer operates as intended. The PTFE tube exiting the buffer needs to clear the AMS clip going into the back of the printer. This prevents any unwanted resistance to the buffer and let‘s it operate as intended. If not, you can see what looks to be like a partial clog or even failure to retract filament.

The print profile is no longer public

Quick and easy print. I pushed the tubing as far into both sides as so could but the filament still grabs onto something when loading new rolls. I went ahead and just ordered connectors from Bambu Labs website. It serves its purpose.

@BrandonRaineri

Which side is it getting stuck at? You should be able to feel a transition from the PTFE to splitter but need to know which end. And you printed V2.1 correct?

@Codyinbody3

Replying to @BrandonRaineri :

correct and its on the end where there's two slots. I have to wiggle it a bunch to make it go in. I printed two at different orientations to see if it was printer error and it was the exact same on the X1C as the P1S.

@mwicks97

same problem happens with mine, even with countersink there is something snagging the filament and gets stuck

Printed in Bambu ASA, turned out great!

@NicolajMa

I printed the splitter in ABS, snap rings in PC. The release ring was printed in PLA-CF but they all snapped on removal from build plate so not pictured.

@BrandonRaineri

Yes, I’ve notice the printed release rings are quite fragile. You can try using the Bambu scraper to get under them to pop them off the bed but not sure how they will hold up to repeated use. I created a plate with the printed ones to make it easier for someone to print everything on one place but I personally recommend using the McMaster fittings if you can get them. They are fantastic and have proper metal gripping teeth.

@BrandonRaineri

You can also try printing the release rings out of PC or PA if you have it. I’d print them slow and hot for best layer adhesion.

I needed brims for the small parts to not get blown off by my part fan and the clips were too brittle to work in one hole. It catches sometimes pulling from AMS to print.

@Mr.Quen

Great model, thanks a lot! I printed it in Bambu Lab PLA matte with your provided print profile. Turned out really nice. I also did print the release rings in Bambu Lab PLA-CF and the same print profile. They are really strong and I have no issue using them. Maybe you could add the release rings to the raw model files even if you do not recommend them? I had to get them from an other user's project file.
