Simple adjustable 623ZZ filament spool holder for 2020 extrusion

Hi, this is my first upload things.
I like 623ZZ miniture bearing.

This is a simple and easy printable spool holder.
Showing second picture,If you don't have 623ZZ, you can use without bearing.
This is for Aluminium 2020 extrusion.

You needs
2x 623ZZ
2x M3 10mm bolt
2x M3 nut
2x M5 10mm for T-slot
or
4x 623ZZ
2x M3 15mm bolt
2x M3 nut
2x M5 10mm for T-slot
