Filament Storage with Dehumidifier

Created my own dehumidifying filament storage unit. First I bought a small IKEA Billy bookcase (https://www.ikea.com/us/en/p/billy-bookcase-white-80263832/ $29) with a glass door https://www.ikea.com/us/en/p/hoegbo-glass-door-black-20530249/, $45). Since the door doesn’t seal, I got some light foam weatherstripping ($6) and added it to the frame. Then I designed a “snap post” to hold 3/8” round aluminum bar stock. You can get this at Home Depot ($12.50). Much stiffer than wood dowels. The post uses one flat head screw to secure it.  I created two other versions of my hygrometer mounting brackets. These fit the Amazon hygrometers ($6 for both) that I also used with my ACE (see my other project). The final item was the tiny dehumidifier that I got on Amazon (https://www.amazon.com/gp/product/B0CXSNQ6YC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1, $49)  To plug it in, I drilled a hole in the side of the bookcase large enough for the plug and then printed a grommet to fill the hole to stop airflow. Total cost was under $150. At full capacity it will hold 17 1-kg spools. As you can see from the picture of the hygrometers, it does a great job at reducing humidity.
