Dry Box feeding, how I did it.

Dry Box feeding, how I did it.

I live in a high humidity area so I generally print PETG from a Sunlu S2 filament dryer, just wanted to share how I did it to help others.

I had been using this magnetic reverse bowden before I had the enclosure so I reused it. I've read about loading complaints with the enclosure included parts so I just reused this.

Sunlu wedge bowden feed

I used this pass through for the PFTE tube from the dryer to the extruder. I didn't bother to design a wider opening, I drilled it out with a 3/16" drill bit and pushed the tube through.

This setup allows me to feet from the dry box, if I print PLA I plan to use the inside spool and included bowden. When I want to do that I just take the top magnetic bowden part and put it on the Prusa enclosure bowden tube.

   Hope this helps someone.

Thanks for sharing.  I might do a similar design for the other filament dryers I own.  Thanks for sharing.

My printer has the same dual light bars as yours. Thanks for posting photos of it inside the enclosure. I'd been wondering it it fits!

I want to do something similar, but somehow I don't like the idea of having to swap the bowdens. Has anybody ever tried achieving something similar using some kind of a Y splitter right before the extruder?
