Ask HN: What is your money-making side project outside programming?
Breville coffee grinders are impossible to get internal parts for. I designed a 3D printed upgrade for the main wear-part in their BCG800XL and BCG600SIL Grinders.The storefront is through ShapeWays[1] and I use iFixit[2],[3] to drive the traffic. It passively makes enough to cover my own coffee needs forever. I spend about 20 minutes per month fielding questions. This all happened because my grinder failed and I could not get parts.[1] https://www.shapeways.com/product/NASLAGCCP/breville-coffee-...[2] https://www.ifixit.com/Guide/BCG800XL+Grinder+Jamming+due+to...[3] https://www.ifixit.com/Guide/BCG600SIL+Dose+Control+Pro+Coff...
