For moisture-critical filament material, I use a dryer next to my printer. This filament guide provides the ability to print directly from the dryer with filament that is drying at the same time or already dried. It's not really a redesign of the previous models and I created it completely from scratch, but I used the main ideas from those previous designs.
It's easy to print, assemble, and attach to the top of the left or right Z-axis. It can remain installed without further interference if other filament delivery systems are used.
I used original Prusa PETG with 0.2mm layer, 15% infill, no supports or brims. Due to lack of PLA, I could not test it, however, printing with it should work just as well.
Additional parts needed:
- 3 bearing 608 (no matter if ZZ, RS, ...), I use these: https://www.amazon.de/gp/product/B07HGXXX37/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
- 1 countersunk screw M3x6mm
