Re-Spooler stand and drill adaptor

thingiverse

I had some filament rolls that were completely saturated with moisture, making them unusable. So, I invested in a PrintDry dehydrator and rigged up a re-spooling system using my first experience to create parts that would help dry filament more efficiently. The spool stand and roller use a standard 608 skateboard bearing, which is quite common. My PETG printed parts snapped together seamlessly. The spindle bolt has a flat side to secure the bearing mount stubs in the strongest possible print orientation. I did add some supports under each stub and with a light file, they fit the bearings perfectly. The drill adaptor uses a 1/4 carriage bolt that's about 5-6 inches long, along with its square head insert, which locks it to the spindle securely. A single nut should be sufficient. It's essential to use drill rotation direction to keep the spool nut tight. My spool holder is clamped to a bench top using a rolled up towel to add some drag, and I use my free hand to guide the filament onto the new spool while controlling the drill speed with the other hand.
