I want to 3d print a custom computer case, I have the skillset to do so, however, I do not know where to find the technical drawings required. I need drawings for a 280mm Radiator, an ITX Motherboard, and various other parts.
I would research component manufactures web sites. It is highly unlikely that you will find all the information in on location. Here our example web site links to get started.
- NZXT - Mini ITX Computer cases
- Fractal Era ITX Computer cases
- Mini-ITX Mainboard Specification
- Hydro Series™ H100i RGB PLATINUM 240mm Liquid CPU Cooler
Another good place to look for is computer parts trade shows in your local area. With the current ongoing COVID-19 situation not sure if any of these trade fair active.
