Free-standing Spool Holder for 2.5kg Filament Spools

This is a free standing spool holder for 2,5kg spools with 300mm diameter, 102mm widht and 52mm bore diameter which are typical e.g. in europe. Of course smaller spools also fit as long as the width is not exceeding 110mm.

The main body of the spool holder (base) is pretty large and beefy, you need at minimum a printer bed size of 270x250mm

You will need two 608 skateboard bearings. 

The hole diameter in the filament guide is 4.1mm.

You can also find the part as a step file in the attachments, if you want to modify or remix it.
