Spool holder for side 4040

I made this one to be sure it fit my Ender 3 after printing 2 that does not.
It is a side mount spool holder for the 4040 profile.
The spool is just some cms away from the extruder of my Ender 3 and the 1kg spool does not touch the z-axis motor (like the other I printed).
You have to mount the original holder on this one with the original screw.
