I got 100m of string to attach Christmas decorations and it was an absolute mess to deal with because it wasn't on a spool.
So I designed this simple spool dispenser that is easy to print, does not have tight tolerances so that it is easy to print, and is large enough to hold a lot of thread.
I estimate it can hold 300 to 400m of a 1mm thread (~100m on the picture).
You can use any settings that you want to print it, but I would recommend to use 0.6mm line width to print the frame faster.
You will most likely need supports for the curved area.
