Custom spool holder extension for your UP BOX or UP BOX+ 3D printers.

Perfect for most 1kg rolls of filament, while also retaining the ability to use Tiertime 500g rolls.

This design also clears the larger magnetic filament cover/door.

We recommend printing at at least 65% infill, with supports.
