Filament Spool holder for extrusion frame (3030)

I made this simple filament spool holder after I couldn't find the one for my purpose. A simple design I made to handle the 4 types of filament spools I have at my house. Therefor the placing of the bearings.

I Uploaded two designs. One, the orginal design (v1.0) and one more stronger (v1.1) if you prefer that. The holes for the screws are 5,5 mm in diameter

You need to print one filament spool holder and two pins. The bearing to use are two simple 608.
