Prusa CORE One Mini Prototype Update: Exoskeleton Complete, Electronics Next

Structural Frame Complete

The Prusa CORE One Mini project has reached a significant milestone — the exoskeleton and base plate are now complete. According to the latest update from creator "suit," all frame parts are tuned and the whole structure is square and aligned.

Structurally the printer is now where I wanted it to be - at least the boring part of the build with the tedious preparation of parts, wrote suit in the latest project update.

Moving to Electronics

With the mechanical structure finalized, attention has now turned to the electronics. The current focus is on the WiFi module — experimenting with positioning to find a few extra millimeters to fit it at the original position.

The biggest question marks at the moment are the heatbed wiring. Some cables will likely need modifications, especially the LED strip - shortening, soldering, crimping new connectors, or making custom cables to get everything routed cleanly in the smaller chassis.

Next Steps

The next phase involves dry assembling the back panel and heatbed carriage — critical components that need precise fitting before the next batch of parts is produced. A mock-up heatbed carriage printed from PLA is being used to verify fitment.

The Prusa CORE One Mini is a community-driven project to create a smaller version of Prusa's upcoming CORE One printer. The project is being documented on Printables, where makers can follow the rocky road to a working prototype.
