Amiga 500 Power Supply Bracket for Meanwell PT-65B

thingiverse

Bracket to fit a Meanwell PT-65B (and likely similar models) into a particular type of Amiga 500 power supply housing. The model number written on the PS case is 312503-03 16121. Suffice it to say, it is a later model of A500 PS with a switchmode power supply innards. Most of the A500 PS I have encountered had posts that prevented the Meanwell from sitting flat. However, this bracket is for the A500 PS models that have posts further apart that allow the Meanwell to sit flat. The brackets are symetrical, which means just print two of these and you should be good to go. The thickness of the bracket is closely matched to the thickness of the original PS PCB, so the case screws back together nicely :) Disclaimer: Do not attempt to modify high-voltage parts unless you are familiar and careful.
