This is a repair of a marshall key holder part.

Unfortunatly as time moves on it tends to fail as the plastic fatigues after many uses.

• Needs support inside to avoid it deforming. I left the support inside to make sure it has some resistance coming in and out of the holder.

See 3mf file for already adjusted supports.

• Perimeter: 2
• Infill: 15%
• Filament: Mine is out of PLA so this should work for most use cases.

If any adjustments needed, please let me know.
