Presta Valve Cap for Bicycle Tubes

thingiverse

I conceptualized a Presta type stem valve cap that's inspired by the shape and feel of electrical wiring nuts, aiming for a design that diverges from the traditional cap layout. This design incorporates built-in support to safeguard delicate details on the flat end, eliminating the need for supplementary supports. When 3D printed, the support can be easily removed by twisting or snipping it off with a razor blade. The model doesn't include pre-cut threads. Instead, the Presta valve's threads – which are 5V2 (measuring 5.2mm in diameter and 1.058mm in pitch) – allow the cap to thread onto the valve seamlessly without any issues due to its matching 5.2mm inner diameter.
