Mini Power Supply (DPS3003 and Laptop Supply)

thingiverse

I decided to house a Rui Deng DPS3003 and a Sony Vaio laptop power supply, model 101310-11, which I happened to have on hand. I wanted something without any internal mains wiring. The laptop power brick puts out 19.5V up to 2A, making it perfect for small projects at 12/5/3.3V. This case is very specific to the Sony laptop power supply as it was designed to allow it to slot in without fixings and then be held in place. There's a cutout for the mains cable on the side that plugs directly into the supply. The laptop supply has a shielded type cable, so you need to get creative hooking it up. Otherwise, it's very straightforward. For those who want to modify, STEP files are also included and can be accessed in the Onshape document if you want to do more. For those interested, there is an Onshape document available for this project: [Mini PSU Case for DPS3003 and Sony Laptop Supply Onshape Document](https://cad.onshape.com/documents/cfd2150d53ad3760c1280e82/w/c48231edbe5c6b61c24e81bb/e/2351edbb93254ce59829681f). A few notes on the design: To assemble, you'll need brass hot press inserts for the top of the case (up to 6mm deep but shorter works as well) and 6 x M3x40mm screws. You'll also want some screw terminals; this case was designed for [these ones](https://www.aliexpress.com/item/32871901542.html). A bit of wire, crimp connectors, and ferrules, and you're good to go. The little hole on the rear of the case is there so you can see the power supplies LED when it's on. I inserted a piece of clear Nylon filament as a light pipe and glued it in place. This is optional.
