derSchraederFlatter - Tire deflator for Schraeder valves

cults3d

A word about the name. Yes, it looks like German, but I'm pretty sure it isn't. While designing it, I came up with the name and realized it'd be a fun tip of the hat to some very talented German designers I've met on Thingiverse, such as CBiker, Modellaner, and several others. CBiker was one of the first I came across with a ton of brilliant designs when I started here, and it was Modellaner's work on the spoke tension meter that led to many awesome discussions. Update: I've posted a complete redesign that does the same thing but is a quick release design so installation and removal are both far easier. While working on bikes, it's often necessary to deflate a tire to change a worn out tire, to inspect the inside, or to replace sealant. With a tire having a Schraeder valve, it's easy to grab a small screwdriver or hex wrench and hold the valve open, allowing the air to escape. But what if you could be doing something else instead of waiting for the tire to deflate? I've already figured out how to turn a generic Presta valve cap into a deflator and use them often (I'll document that simple process and share it) but occasionally get to work on bikes with Schrader valves, and the same trick doesn't work. Enter this handy little tool. It's a simple thread-on design with an integrated pin that will hold the valve open for you while vents allow the air to escape. Need a flat tire? Take off the valve cap, screw this on, and you can continue doing other things while the tire deflates itself.
