Spool Holder With 608 Bearings And Pneumatic Fitting Mount

This is a small spool holder I made to fit my printers. It has a mount for a M6 pneumattic fitting and 9.5 mm hole for a 10mm pneumatic fitting (make the threads yourself screwing the fitting in gently) as well as holes to mount it on a flat surface.
The spool holder is made for 72mm wide spools

These are the pneumatic fittings I used :
