Filament Dehydrator Spool Adapter

The base is engineered to accommodate an unconventional bearing. The diameter of the bearing is 1.210 inches by .375 inch, respectively. It's located here.... I've included step files for you to modify according to your chosen bearing specifications. The hole in the platter measures 3/8 inches in diameter. Three bearings are installed on the platter, each with standard dimensions of 10mm outside diameter x 3mm inside diameter x 4mm thickness. These are the same type used by the Titan extruder for rollers. I utilized a $26 Rosewell dehydrator purchased from Amazon, and this setup performs similarly to the $130 units specifically designed for 3D printer filament. A standard 1-inch ACME thread was employed for the nut and platter interface.
