Bring your Prusa CORE One or CORE One+ up to second-generation spec. This easy-to-assemble kit from Prusa Research adds a redesigned heatbed mounting, GT1.5 belts and an integrated nozzle wiper, so prints start sooner and cleaner, and smooth surfaces look better.
What the upgrade gives you
-
Faster print starts – the redesigned heatbed mounting (Gen 2 expansion joints) removes the separate “Absorbing heat” wait for materials printed at bed temperatures up to 85 °C, and shortens the wait for hotter materials.
-
Smoother-looking surfaces – GT1.5 belts and pulleys make repeating belt patterns finer and harder to see, most noticeably on large, smooth faces.
-
Cleaner print starts – the integrated nozzle wiper cleans filament off the nozzle before each print, keeping stray strands and small blobs away from the print surface.
In the box
- GT1.5 belts and pulleys
- Expansion joints (Gen 2)
- Nozzle wiper
- Spare nylon rivets
Compatibility
For the Prusa CORE One and CORE One+ only. It does not fit the CORE One L (see the CORE One L to CORE One L+ Upgrade Kit), MK4/MK4S, MK3 series, MINI, XL or HT90.
Good to know
- Self-install kit. Follow Prusa's official assembly guide and update the printer to the latest firmware afterwards.
- The easier-to-remove top cover fitted to new CORE One+ (Gen 2) printers is not part of this kit. It does not affect how the printer performs.
- Genuine Prusa Research part.
