Radiator Bleed Key / Entlüftungsschlüssel für Heizkörper

thingiverse

The warm months are dwindling, and the house is rapidly losing heat because of clogged radiators! Lucky us, we just so happen to have access to a 3D printer at home. With this thingamajig, making your very own radiator air release key is a breeze. To get started, simply press out three 5mm square nuts from a standard cartridge. Now place them inside a 10mm hole; it's really that straightforward. In case things get tricky, you can try carefully applying some heat using a lighter until the nut drops right into position. So far so good! As for printing details: Rafts: no problem, none needed here. Supports: let's save the supports for another time, thanks! Resolution: set it to 0.2mm, that's a given when we're dealing with intricate parts like these air release keys. Infill density: bring it up to 70% and watch your prints thrive!
