Small 2-in-1 PTFE adapter for H2D. If you are tired of constantly changing the PTFE tube back and forth when printing TPU, then this 2-in-1 PTFE splitter could be something for you. It is easy to print and takes up little space. The adapter is simply plugged together and does not require any screws.

What you also need are 3 Pneumatic Valve [https://www.amazon.com/-/en/dp/B099FG52D4](https://www.amazon.com/-/en/dp/B099FG52D4)

I've added a brim for better adhesion. As the walls are very thin, take care when removing the brim. You can of course also try to leave the brim off.

The adapter has been in use for some time now and works perfectly for me. The existing eyelets are sufficient for fixing the adapter. I used PETG and the filament glides smoothly through the adapter. 

Before using the adapter, make sure that the valves cannot slip out (simply pull on them). When this happens, glue the two halves together with a little superglue. Glueing is recommended in any case because of the H2D printer's high viberations.

Assembly is simple (see pictures) and requires no further description…
