Inwin 301 Magnetic Rear Fan Filter Adapter

thingiverse

The Inwin 301 case is a solid choice, but the rear fan would work better as an intake. Unfortunately, it doesn't come with a filter, and the case's design makes it hard to screw in a flat filter due to the bulge around this area. This 3D printed adapter will provide a better fit for a Silverstone mesh filter. It attaches to the case using magnets for easy removal and cleaning. The magnets are press-fitted but may be loose depending on your printer settings; if so, add a small amount of superglue to secure them in place. Printer settings: PETG is probably the best choice because computers can get quite warm, and PLA might soften. Print with supports since they will need some small pliers to remove from the rails. Adding horizontal contraction will help ensure everything fits properly without being too tight.
