Seeing more blind enthusiasts buy 3D printers, which is good, but too many are buying Ender 3, which is bad, at least for blind people. If you hear of someone being interested, tell them to get a Prusa. Enders use inaccessible touch screens. Prusas have a basic LCD with a click wheel, menus that don't wrap, and have sound feedback. Printers require frequent calibration, which is manual, and largely inaccessible on Enders, but automatic on Prusas.
