Filament Dry Box with Rollers

Using the standard cereal box available from Amazon as used in the GunplaMark design I made some modifications as listed to improve some components. A heads up on reactivating the silica gel. According the mfg you can put it in the microwave for 10 min. I practically had in for almost 30 min in 10 min intervals and all it did was sweat out the moisture but never reactivated as it should. So I put the saturated gel beads in a open jar placed it inside my filament dryer at the highest temp of my dryer at 70degC and after 12 hrs gel reactivated to their original orange color. Actually not quite the same original bright orange but good enough to see that they can be reused.
