Longer tube for Anycubic I3 Mega Spool Holder

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3606863.

I have some spools which are too wide for the original tube, so I made this one which is 15 mm longer. You need the holder from the orginal Thing: https://www.thingiverse.com/thing:2720207
