Anycubic I3 Mega spool holder

This is a simple spool holder that uses the metal tube from the original I3 mega spool holder.
For assembly you will need 2 or 4 m3x10 screws (original screws will be to short) - I only used 2 screws on the left and it holds up perfectly.
But if you want to use all 4 screws you will first need to undo the left 2 screws from the printer, then screw on the holder, only then undo the right 2 screws, put on the printed washers and screw in the new 10mm long screws (for both screws on the right). I designed it this way so that two screws are holding the printer together at all times (probably a little overcomplicated :) ).
I also left holes for the tube a little bit to small so that you can insure a tight fit by sanding it.
