Mini Spool Adapter for UM3 Series

youmagine

I designed two adapters for the UM3 series to hold mini-spools like those on Taulman 1lb spools. The small version doesn't have threading, while the full version does. I made them because rewinding that stuff onto a full-sized spool was hard and keeping it straight was even harder. These adapters also keep the netting in place as recommended by Taulman. They're designed to be flexible. There are two versions so people can choose which one they want to use and print. All pivot points are aligned to create an interior double wall that's stronger than a 90° angle for the holder to the spool rod. This is shown in one of the pictures. You can also choose individual infills as you like. I prefer the full holder because it aligns the filament better when feeding it. I included both the adapter and just the spool so users have flexibility. This print still needs some work to look good, but I wanted to get it up. It needs a bit of cleaning. I printed it in polycarbonate for strength, which makes clean-up difficult - three X-Acto blades so far.
