Overall, I like my Fixdryer 1. However, what bothers me is that there's no way to maintain the dryness of the filament during storage. That's why I designed these plugs to be able to close the holes. These plugs will work with the Fixdry 1, or every dryer that is identical in construction (Aomdom, Hlieeosfcn, etc).

You have to print w top side covers, 2 side covers and 1 top middle cover to be abled to close all the holes. Since the plugs are made of TPU, you should still be abled to use some of the holes, but still let the plugs of the other holes stay in place, bending the rest out of the way.

They are designed to be 3D printed in TPU and fit quite snugly, so you don't have to overextrude. 95A shore hardness TPU is what I used, but I generally think softer TPUs might work a little better. Have fun printing!
