Prusa Enclosure Spool-holder-R with arm shifted deeper

The problem

The original Spool-holder-R causes some filament spools to scratch against the door when the extruder pulls on the filament, causing visible scratch damage to the door.

When the air filtration fan is on, this intermittent contact also causes a bad rattle noise.

This fix

This part provides a quick fix by adding 25mm of additional clearance.

Printing

Same as the original instructions:

• print settings: 0.20mm QUALITY
• filament: PETG (tested on Prusament)
• 15% grid infill

Installation

Drop-in replacement for the original Spool-holder-R: 4A > Step 37.
