Spool for trimmer line

This is a 3D printer filament spool intended for use with Nylon trimmer-line, which often comes without a spool. Re-spooling nylon trimmer line is an epic PITA, so I designed this to make it a bit easier to use.

If you want to dry out the filament while on the spool, make sure you print this out with either PETG or ABS. I don't recommend PLA.

The "-55" versions have a 55mm hole. The other version has a 40mm hole.

The "Alt" version is an alternative design that is more sturdy and uses less filament to print.
