I wanted to feed from my filament dryer without giving up the automatic feeders. I didn’t like any of the options out there, so I designed my own. After many iterations, I have landed on a much more elegant design than I had envisioned when I first started. Very happy with the way it turned out.
Same design works for both left (1 & 2) and right (3 & 4) automatic feeders.
Doesn’t obstruct the toolhead numbers or the status LEDs.
Printing is quick and easy: ~35 minutes for 2 copies. No supports. ~26g of filament
Installation is quick, easy, & secure: No mounting hardware required.
Good idea. You also don’t have to drill or replace any original parts. However, I wonder whether the feed might jam if this custom part shifts even 1 mm to the right or left?
Shifting cannot happen because there are 1mm protrusions that align and hold the front of the adapter in place. The rear also has protrusions that lock into the holes of the feeder body. The entire adapter is very snug and rigidly mounted once installed properly by simply snapping into place..
For those of you with M10-threaded pneumatic connectors (e.g. PC4-M10 or PC6-M10), I’ve added a new model/print profile with larger openings for the M10 threads. It’s a bit bulkier and a takes a few minutes longer to print, but you now have the option to use M10 threaded connectors for 6mm PTFE tubes if you like. https://makerworld.com/en/models/2176077-snapmaker-u1-ptfe-adapter
Here’s an excerpt from a Reddit forum… but you can also find this information elsewhere online…
… the thread is 1/8" BSP. This is the most common pneumatic connector used on 3D printers, actually 9.73 mm outer diameter x 28 tpi, and very close to 10 mm x 0.9 mm pitch…
It can be easily inserted as a thread in Fusion 360. Works great.
Are you saying the seller misrepresented the product I ordered? You did get me curious so I checked with my thread-checker and it’s definitely compatible with M10-1.0 so .
Yes. Zero resistance, but the thread length is only about 5mm long. How far do you expect 1/8-BSP male can go into a female M10-1.0 before binding-up?
Anyway, I’m not sure why it matters at all and what is your point? This post is about the adapter, not about the particular pneumatic connector that I had on-hand to demonstrate functionality. The adapter is designed for metal threads of approximately 10mm in major diameter to thread into a hexagonal hole. Both M10-x.x and 1/8-BSP (9.73mm nominal) will work regardless.
I received a very good suggestion in the Makerworld comments to support ECAS04 connectors/fittings because they are much lower-profile than the M5/M10 fittings. I agree and so I have added a new variant:
