Works With Your Original Prusa® CORE One L to CORE One L+ Upgrade
Upgrade Kit
CORE One L → CORE One L+ Upgrade Kit
Two changes that make every print look better.
A small, easy-to-install kit that brings an existing Original Prusa CORE One L up to CORE One L+ specification. You get the new GT1.5 belts and pulleys plus the integrated nozzle wiper — the two hardware changes that account for the visible print-quality difference between the two machines.
Preorder — expected to ship Mid-October. Order now to hold your place in line.
What's in the Kit
Motion
Belts & pulleys GT1.5
A complete set of the finer-pitch GT1.5 belts and matching pulleys used on the CORE One L+.
Print Start
Nozzle wiper
The integrated wiper assembly that cleans the nozzle before the first layer goes down.
Hardware
Spare nylon rivets
Replacements for the rivets disturbed during installation, so you are not hunting for parts mid-job.
What It Does
Smoother-looking surfaces
The GT1.5 belts make unwanted repeating patterns finer and much harder to notice. On a 300 × 300 mm bed you are usually printing large, smooth faces — exactly where even subtle vertical fine artifacts stand out most.
Cleaner print starts
The nozzle wiper removes filament residue from the nozzle before printing begins. Fewer loose strands and small blobs dragged onto the first layer, and a more consistent pre-print calibration every time.
Who It's For
- You already own an Original Prusa CORE One L and want it printing to CORE One L+ standard.
- You print large, flat-faced parts — panels, enclosures, cosplay shells, display pieces — where surface artifacts show.
- You run the machine unattended and want a cleaner, more repeatable start to every job.
