Vỏ Mean Well RT-65B cho PSU Amiga

I have done a few different power supply cases. This one is by far the most sturdy and best I think, though it is my first in FreeCAD. The Mean Well RT-65B is more than enough power for almost any Amiga that uses the square power connector. (The RT-50B is probably also enough... though these are similar the mount holes are not, so RT-50B will not fit.) According to the manufacturer it does not have a minimum load requirement on any of the outputs so compared to model PT-65B you don't need any load resistor. It comes in a caged chassis which is easy to mount and connect.

The PSU sits inside a ridged base in the printed box and two bolts secure the PSU. You must not use long bolts here or they could damage the PSU! 6mm, no more. The PSU is further secured by the lid of the case which has ridges that contact the top of the PSU and keep it from escaping the ridged base even if the two bolts on the bottom are not there. The lid engages with the base by the four corners but also through keys in the middle of each side. With other printed PSU boxes I have noticed flexing but that should not happen here.

Canadian Tire were clearing out some trailer cable bundles for $3 so that's what I used, it is inside some techflex-like stuff that came with a cable tidy shelf kit. Apart from that you need a power inlet, cable strain relief and of course the square Amiga power plug. I used a C-14 socket with integrated switch (illuminated) and fuse. It snaps into the case. I also used a PG9 cable gland with a 15mm hole. This is not for waterproofing but strain relief, of course there are ventilation holes and this is in no way intended to be waterproof.

Four M3 brass inserts are added in the base to secure the lid. Lid bolts can be a wide range of sizes, I used 14mm. Shown printed here in Tecbears matte blue PETG which for the price was a pleasant surprise, 0.40 nozzle, 0.20 layer height, 40% infill.

The usual disclaimer: unless you know what you are doing do not wire up this project, it involves mains power and could easily kill you. It could be illegal for you to do this without an electrician's license depending on where you are.
