Side Spool Mount for Creality Ender 3 or 20-4040 extrusion

I tried a different side spool mount on my ender 3 and the filament feed was improved but the mount wasn't high enough to hold the spool off the table. So...I designed my own and here it is. It is also my first submission to thingiverse so let me know what you think.

This design offers the following:
1. The spool can be mounted anywhere between perpendicular and 60 degrees to the extrusion.
2. Allows 8mm "extension" when used on an extrusion with 20mm slot spacing.
3. This mount should fit
