Open-Source RGR EZBuff Can Restore Your Scratched Game Discs
The open-source RGR EZBuff is a 3D-printed disc buffer and resurfacer that can revive scratched game discs without the high cost of commercial machines.
Dennis van den Broek, known as PointerFunction, has released a fully open-source disc polishing and resurfacing machine called the RGR EZBuff. The 3D-printable device is designed to recover scratched games, music CDs, and movie discs that would otherwise be considered broken. The timing is pointed: Sony just confirmed it will stop manufacturing PlayStation discs after 2028, and Microsoft is widely expected to go discless with its next Xbox.
Van den Broek says he built the EZBuff because commercial disc repair machines either cost too much or demand per-disc consumable fees. The EZBuff uses off-the-shelf parts and can be constructed from a single 1kg roll of filament on a small printer like the Bambu Lab A1 Mini. Felt pads handle polishing; high-grit sandpaper can be swapped in for deeper resurfacing, though the creator recommends a second machine if you plan to do both regularly.
The machine won’t fix disc rot or data-layer damage, but it has already rescued thrift-store finds the creator thought were lost. No one is selling pre-assembled units yet, but the build files are up on Printables, and RetroRGB has posted a full interview. If optical media is on its way out, a cheap community-built buffer is a good thing to have around.
