The GratKit Firefly filament dryer is great and Tuya connected, but lacks proper PTFE tube connections. I made this adapter for both M6 and 1/8" NPT connections. You can use any size tube (I used the standard 4mm).

For this particular build I used my Qidi Q2 with their ABS Rapido. Any suitably heat resistant and firm filament will work.

-0.16mm layer

-standard settings

-25% gyroid infill

-organic supports (see images)

To mount it, choose a location near the centerline of the dryer (avoid the display cable!). I matched up the top of the adapter to some of the mould lines. Use a rotary or other cutout tool to make a hole in the plastic cover the same size as the underside recess of the model. Get some 3M foam tape for a solid mount.

Screw in your M6 or 1/8" NPT PTFE adapter (it'll require a small wrench to tighten/clear out some print variances). 

Push in your tubing, feed the filament, and get printing!
