This project was built specifically to fit a Fractal Define S2 chassis. The Define S2 chassis is both long enough and has a mount on the bottom for a 240mm radiator. This radiator mount is repurposed to be a mounting point for the PSU adapter.
Everything you see here was printed using a Prusa MK3s and Prusament PETG filament. Every piece of this design prints well without any supports. If you print a single copy of each object, you will probably exhaust an entire 1 Kg spool of filament.
