RGR ezBuff: An Open-Source, Fully 3D-Printable Disc Restoration Machine

Dutch creator Dennis van den Broek, known online as PointerFunction, unveiled the RGR ezBuff on June 30, 2026, a disc polishing and resurfacing machine designed to be entirely 3D-printed at home. The device gives scratched or grimy CDs, DVDs and Blu-rays a second life, at a fraction of the cost of commercial machines, which often charge subscription fees for consumables.

The product of seven years of research and plenty of failed prototypes, according to its creator, the RGR ezBuff was designed to stay affordable: every part can be printed from a single 1kg spool of filament, and the model was optimized to fit the build volume of small printers like the Bambu Lab A1 mini. The machine can buff out light surface scratches and clean off surface contaminants, with an optional expansion for resurfacing the deeper scratches that can render a game unreadable.

Described by its creator as "my birthday gift to the community," the RGR ezBuff remains fully open-source and free, plans and parts list included. It cannot, however, do anything about "disc rot," the irreversible chemical decay of the data layer that affects some older optical media.
