Filament Dry Box

Print 2 of Top A and 2 of Top B for all lids , lay them flat with posts going up.
For the hanging round print 2 window, and 1 window Ptfe , and 1 window Meter . For windows if printing in clear or transparent no infill print solid by changing top bottom layers to 6 or more.
Meter hole is for the standard Hygrometer found here https://www.banggood.com/Digital-Cigar-Hygrometer-Thermometer-Humidity-Monitor-Meter-for-Humidor-p-1095668.html?rmmds=myorder&cur_warehouse=CN&ID=224
Assemble box (I use gorilla glue) Glue set ring to the 2 base pieces. It will spread enough to load spool with the core in it.
When done to increase clarity clear coat both sides in and out also to seal it if you are printing in pla.
There is a tray in the bottom to use loose desiccant like silica cat litter (cheapest option)
