Prusa XL Spacer for 300mm Spools

I have some filament shipped on 300mm spools according to DIN EN ISO 544. Using 2 of these spools with the Prusa XL is possible. But if the printer is equipped with the Enclosure, there is a potential blocking by the handles of the bellows.
So, to avoid an issue during printing, I designed this spacer which simply can be clipped onto the spool holder.

Printing

• Filament: ABS, PETG or similar.

• Infill: 20% is enough

• Support: not needed.
