Ender 3 spool holder extender

Update: You may need to print it 103% of scale to fit it for you as some of the comments implied.

Inspired by https://www.thingiverse.com/thing:4316465 I made some changes:
- instead of threads I changed it to be twist-fix
- aimed to copy the original holder in terms of shape and size

Supports are required, but not everywhere. I attached a gcode file with supports where needed, and blocked supports where thought them unnecessary.

gcode file is sliced for:
* rafts
* 0.2 resolution
* 20% infill
* 90% flow (probably not required for most of you)
* 50 mm/s print speed

Print time from Cura:
~4h
29 grams or 9.58m of filament


I know it's not ideal - I am still learning :)
