Ender3 V3 SE spool holder frame, balancing weight to the center

The spool is rotated 90º, and moved so that the spool hangs above the gantry in the middle of it, making centre of the mass right at the center. It zeroes out all possible torques caused by filament weight, resulting into more consistent printing.

• Easy to print
• No additional screws needed
• Reinforced by using 3D-printer's original steel spool holder
• No support required
• 20% or more infill is recommended

UPDATE: Added a variant with pins (not tested!), that should make it double-sure the holder would never detach accidentally (although it wouldn't detach even without the pins).

UPDATE 2: Added elevated version, for 2kg large diameter spools.
