cap for the regulator of an underfloor heating

thingiverse

Most of the plastic caps for the regulators controlling underfloor heating in this house failed over the years. Some rooms were consistently hot, while others remained cold.\r\nMy father couldn't find replacement parts, so he considered replacing all the valves and tubes. This option was far more expensive than purchasing a 3D printer, which is why I convinced him to buy one. With the new device, I designed the cover shown here. After two years of use, 16 of these covers have performed flawlessly without any issues.\r\nThe contraption was built with shrinkage of nylon during printing in mind. Through holes on the sides allow checking the screw position.\r\nUsage:\r\nI printed the cover using Nylon from Hobbyking at approximately 250°C and 100% circular infill. Although it's been a while, I'm not sure what other parameters I used. However, I do remember that Nylon was a poor choice for starting 3D printing due to excessive warping and being extremely picky about its surface.\r\nAfter printing the cover, insert a hex nut and screw in a roughly 30mm long screw through the base surface hole. Secure the contraption on the valve with two strong cable ties.
