Good news for all makers and optimizers: Prusa has released the completeCAD files of the framesfor the newCORE Oneand theCORE One LSo if you've always wanted to take a virtual look under the hood or are planning precise accessories, you can now download the STEP files and Fusion assemblies.
But the real bombshell lies not in the files themselves, but in the fine print.
The "Open Community License" (OCL) – What is that?
With this release, Prusa is moving away from classics like GNU GPL or Creative Commons and introducing theOpen Community License (OCL). Why? Because classic software licenses often do not fit one-to-one with physical hardware.
What is allowed:
Learning & Analyzing:Take a look at how the professionals constructed the frame.
Modding:Create your own extensions or modifications.
Spare parts:You are allowed to make parts for your own machine (private or commercial) yourself.
Workshop Planning:Integrate the model into your digital layout.
This is taboo:
Commercial reproduction:You may not sell complete printers (or remix kits) based on these files without a contract with Prusa.
Focus on "Right to Repair" and AI protection
Especially interesting: The license contains explicit clauses regardingRight-to-Repairand simultaneously protects the data from unsolicitedAI data mining. Prusa makes it clear: Whoever buys a printer owns the hardware and can do what they want with it. The license solely regulates the handling of the intellectual property of the digital plans.
My conclusion
Prusa is trying to strike a balance here: The community gets the resources it needs for modding, while "copycat manufacturers" are legally restricted. Whether the OCL will establish itself as a new standard in the industry remains to be seen.
What do you think of this step? A fair deal or too restrictive? Let me know in the comments!
