Vacuum Tank Air Dryer!

I've been experimenting with using a 5-gallon vacuum chamber for drying/dehydrating my 3D printing filament. When repressurizing the chamber, I was letting some hydrated air back in at velocity. To fix this issue, I created an Air Dryer attachment that threads onto the 1/4-inch pipe threaded inlet of the unit. Inside the dryer, a desiccant pack wicks out moisture from the air entering the chamber. Two sizes are available based on the size of the desiccant pack used or reused: small and large. I also added two mounting holes for M3 bolts to hold the cover/cap onto the body. You can force tap the M3 bolts, but a speed tap is handy for creating a quicker and cleaner fit.
