Filament Spool Carousel for use in Dehydrator

thingiverse

I had a bag of 3/8" ball bearings lying around so I decided to make a carousel spool holder to mount inside my food dehydrator so I could keep those pesky hydroscopic filaments (nylons, TPUs etc.) dry. The geometry prints without supports. Snap 8 3/8" ball bearings into the center ring and you've basically got yourself a lazy suzan. Then you can attach it to the bottom rack of your dehydrator however you like. I've put loops on there so you can use zip ties if you want. I just glued mine in. I attached a bowden tube to one of the rings in the dehydrator so I could feed filament through to my extruder and just like that, I now have dry filament. Depending on how hot you want to crank up your dehydrator, you may want to print this out of something other than PLA. I used PETG and it works great.
