AMS Buffer Injector Guides

The best PTFE guide plus PTFE Release (no tools require).

There it is. Many Makers asked me for this after seeing the one I designed for the AMS Hub.

Since the location is good, I didn't add a subplate and relocate the buffer. The drawback is that I only have a little wire management.

In a certain way, it's better because there are no holes to tap or screws. It just "Smap in place".

It's also easy to assemble;

-Release the two PTFEs from the buffer.

-Snap the central part on top of the AMS Buffer. (See the pictures above) (injector end first and snap the other end)

-Slide in the two PTFE guides and secure them with the "C" ring. (The longer one goes in the Injector side)

-Push in the two PTFEs. Tug them back to see if they lock in place.

It's ready to go. Thanks to the realignment of the PTFE in the fittings, you won't need other tools and will avoid jams.

It's not a bad idea to chamfer the inside of the PTFE after cutting it.

After printing, make sure the holes are clean. The guide should slide easily and freely into their mount. It may require a little filling in the bores.

I did test it with PLA. And the small tube broke. Then, No, you can't use PLA.

I test-printed it with PETg, which prints well for the P1P one. It works well, and no support is needed (But it can't hurt). I didn't have to file or sand the bore, but it may be required (Especially if you use generic material and print on a series P1; the flow is critical). The injector side guide must slide freely, and the PTFE should slide into the guide freely. It doesn't matter if the PTFE slides into the guide or the guide slides with the PTFE.

Of course, I did make it in ABS. It's the best for me and my favorite BBL Blue ABS.

It prints in an hour and a half in PETg and is even faster with ABS.

Enjoy.
