I absolutely love my SUNLU FilaDryer S4. Using it to dry filaments (of course) all the time and as a filament holder when printing from a side of AMS. But there is one very annoying me thing about it. Especially if I print out of it and roll got tangled, so I have to open Lid a lot of times to sort tangle.

And what is annoying me so much are small lock Knobs you use to open Lid. They are small and hard to hold, especially with my sausage like (LOL) fingers. So I made those Knob to make them much easier to use. At least this helped me very much. And if I'm not the only one with this annoying problem, I'm happy to help with this little add on.

I have made two different Covers.

1. Smaller one. Comfortable enough and looks neat in my opinion.
2. Larger one. Bit wider and better grip especially if you have a big fingers, but looks a bit more bulky.
    

I like both versions, You can choose one You like more.

Two small TIPS

1. Putting Knob Cover on could be a bit tight. So I recommend to support Knob with fingertip or some kind of a stick from opposite side (through the cover Opening). Just small precaution to prevent even a smallest possibility to damage original Knob!
2. PLA as build material here should be just fine, but as it is a Filament Dryer and so it heats up, preferable material to use here should be with some heat resistance such as ABS, ASA or at least PETG.

You can Buy me a coffee if You feel good doing so :)
