Description
Give your Prusa CORE One+ a cleaner look with this custom-designed decorative cap!
This small plug is specifically designed to fit into the cross/plus-shaped (+) hole found on the updated Prusa CORE One+ Spool Holder. It has a purely aesthetic purpose, helping to hide the internal opening and complete the look of your printer's side-mounted accessory.
Key Features:
Perfect Fit: Designed with loose tolerances to ensure the cap can be easily inserted and removed by hand.
Safety Tip: If the fit is too snug on your specific print, you can easily pop it out using the tip of a hobby knife or cutter.
Themed Look: Matches the official Prusa aesthetic perfectly when printed in orange.
Recommended Print Settings:
Printer: Original Prusa CORE One
Filament: Prusament PETG Orange (or any PETG)
