This is a simple holder for a 63mm wide roll of solder thread, with a hole diameter of 11.5mm. I made this because I wanted a convenient holder for my roll of solder thread. The roll simply clicks into place and the little "goal" in front keeps the thread from tangling. It's nothing fancy, but it gets the job done and is easy to print.

Slightly scaling down the parts that goes into the base can make it a bit easier to assemble.You may need to file or sand the "feet" a little to make them fit into the base when assembling it. I made it for 0.9mm solder thread, but it should work with slightly thicker thread.
