Description

Y-Splitter for Bambu printers, and any other need for a PTFE Y-Splitter!

  • Highly Optimized to work well, I've printed many hundreds of hours with mine fitted, including prints with hundreds (if not thousands) of filament changes each, and never had one problem.
  • Threaded for PC4-M10 PTFE Fittings

 

Please Note: Whilst it is possible to print faster (using thicker layer lines or faster print speeds, as per the un-official print profiles), this can and likely will affect performance as it'll affect how smooth the print and the surfaces are inside the filament guides. Please print with the profiles I supplied (Marked, ‘Designer’), I've heavily tested my profiles and can't guarantee that other profiles will perform as I've described.

 

What does it do?

Allows you to connect 2 sources of filament (eg AMS and external spool) without needing to swap over PTFE tubes each time you switch between them.

 

Why this one?

I had tried a number of the popular options around, but found I was often getting filament caught inside it or jammed and it was never something I could rely on to run my AMS through due to the frequent filament changes.

This has taken weeks to refine, and have gone through multiple printed revisions, each one undergoing testing and further refinement and I finally landed on this one. I've done a number of tests and have printed several prints with this connected, each with 50-100 filament changes with zero problems.

 

 

How do I use it?

The splitter has an IN end and an OUT end.
The IN end has two holes, they are both the same and you can run any filament source into either.

The OUT end has just one hole and that should lead to your printer.

 

 

 

Each hole is threaded to take a PC4-M10 PTFE pneumatic mount (the push clips that PTFE tubes slot into).

If you need to buy more, these are high qualty reliable PC4-M10s.

 

Once your PC4-M10's are screwed in, slot in your PTFE tubes.

The PTFE tubes going into the two IN holes you can push in pretty much as far as you want too (I'd advise not as far as they'll go but maybe 2-3mm before that).

 

The PTFE tube going into the OUT hole however is important that you push that all the way in.

As you can see below, a special recess has been designed for the PTFE tube to slot into and it needs to push all the way down into this hole to ensure the inner diameter lines up with the feed hole for the filament. It's also important to make sure your PTFE tube are cut neatly and straight.

 

 

Mounting
You have three options for mounting. I've designed and included two mounts specifically for the Easy Split (detailed below), but you can also just leave it free. I personally have mine connected up and it needs no mount (as pictured), but it depends how and where you'll want to use yours.

  • Fixed Mount:
    The Easy Split slots onto this mount and it holds it in a single position.
  • Swivel / Rotate Mount:
    The Easy Split slots onto this mount and it allows free rotation whilst fitted. It can be good if you'll want to swing it depending on if you're connecting your external source or not.

Both versions are available with holes cut for 8x3 magnets, or 10x2 magnets.

 

I've included a profile which contains all 4 mounts, with each one on it's own plate, so you can just print the one you want from that (or via the included STLs).



Print Settings
I highly recommend printing from the official profile included above as there has been a lot of tweaks made to ensure this performs correctly. If you want to slice it yourself though, here's the core settings:

  • Layer Height: 0.08mm
  • Wall Loops: 4
  • Infill: 15% Gyroid
  • Outer Wall Speed: 45-100mm/s
  • Material: PLA

 

Tips

  • Ensure your PTFE tubes are cut cleanly and straight
  • Print using my profiles (Marked with the ‘Designer’ tag) which I've printed, altered and optimized many times, and heavily tested, to ensure it functions as designe .
  • Although I have included a profile I've optimized for PETG, I'd advise printing in PLA. PLA has zero performance issues for this item and due to the artifacting that some people experience when printing with PETG, PLA will often perform better in this specific case.
  • The mounts are only optional and should only be used if you need it fitted in a suitable place. I personally have it hanging free (as pictured)
  • Whilst adhesion shouldn't be a problem with this design, 2 of the 1200 people who have downloaded the primary profile have mentioned they've experienced adhesion issues, so I've added an additional profile which should help aleviate these issues. I'd suggest trying the main profile ("Highly Optimized (PLA)") first though.

PETG Highly Optimized
Bottom and inside the 2 threads were quite rough, probably still usable. Reprinted on the high temp plate instead of textured pei. Flawless, not sure why the bottom fell off on the first print.

Ah that's very interesting, they shouldn't be rough. Could I ask which PETG you used? Had it been dried at all?

Sunlu, it's plenty dry. Might have just burnt it because it looks like it rippled a little, but inside looks clear.

Ah strange, that's the bed side, it should be completely smooth but looks like there's huge gaps with no infill at all. Out of curiosity, did you check the correct printer and bed were selected in the profile before printing? It's the only thing I could think of.

Glad to hear it, and thanks very much for posting! I'm glad it's working well but I would definitely advise, when you can get some, fitting some PTFE tubing to the external spool pretty as well.

Thanks! Does the trick nicely. Seems very sturdy and didn’t require any post-processing. Will try the magnetic mount.

I used Overture Easy PLA - Digital Blue. Photo doesn’t do it justice, but I really like the colour.

A fantastic model! Printed easily without supports using my P1S and Bambu Silver PLA Basic. Threads worked well with PC4-M10's. Thanks for all your hard work.
