Atari ST PSU replacement parts

The original Atari ST PSU can easily be replaced with a MeanWell RD-35A. However, what I disliked was that the mains wires were not fixed, and the terminals were not protected from accidental touching.

Read my blog article about the modification.

Models

• Terminal cover: Just print it upside down. For me it worked without supports, but YMMV. After printing, just remove the screw left to the terminal block, and fix the cover using that screw. I used PLA, but other materials are fine as well.
• Wire bracket: It is mounted to the original PSU frame, next to the RD-35A. Then use a zip tie to fix the mains wires.
