Ender 3 universal spool support

Fit most spool in width and bore up to 60mm in diameter.

Simply print the parts, then screw and unscrew the conical end nuts a few times to clear the threads.

Reuse the original nut to secure the support to the metal bracket on the printer.

Conical nuts print more easily from the top of the cone to the bottom. Obviously, the tube must be printed vertically.
