Spool Holder for 3030 Extrusions

This is a spool holder for attachment to the Artme 3D filament extruder MK1 to use it as a spool winder

Sometimes you can get large filament spools at a good price, but they're impractical to handle, due to their size and weight.

So I thought, why not "misuse" the Artme spool winder for this...

It does take a little longer (depending on the winder's speed), but for occasional rewinds, it's sufficient for me.

You should stay nearby during the rewinding process to adjust occasional problems - for example, rolling resistance of the counter spool, belt tension of the winder, etc.

The holder is screwed to an approximately 200mm long 3030 aluminum (or printed) extrusion, which stands upright using an angle bracket

attached to the rear end of the extruder leg.

The holder is designed for M8 threaded rods - various spool cones, rollers, etc. can be attached to it.

I'm attaching my version of spool cones suitable for 608 ball bearings.

A piece of PTFE tubing, which is clamped in place of the original tubing, is also required.

The rest is pretty self-explanatory.

For sufficient stability, print the holder with multiple perimeters and higher infill.

For use on the MK2, MK2.5, MK3, MK3S extruder versions... a different attachment method may be necessary, as, as far as I know, the base frame on these extruders is slightly offset compared to the MK1.
