Update 24 Feb 2023: Added new versions (V2) and (V3) with some minor tweaks. Made the claws slightly weaker and the gap for the filament to snap into slightly smaller. PLA print tested working with Sunlu S2 Filament Dryer. A thinner and weaker claw version, V3 is too thin for me to print without a brim or adhesive on the PEI surface, your results may vary.

Printing with dry filament improves print quality.

Most filament dryers available do not have a vent that allows moist air to leave the box.

Leaving a small gap for moist air to escape the filament dryer box will help improve the drying capability of the filament dryer as shown in the youtube video below.

I have a Sovol SH01 so my design is based on that. added a small open hole to allow the filament to run through, since SH01 does not have a horizontal filament guide.

I printed in TPU but i think other materials should be ok.

Take note that PLA or other materials with low glass transition temperature might not be suitable. PLA typically softens around 60 degrees Celsius.

Feel free to feedback if it works for your filament dryer of any brand.
