UPDATED V2 Choke Key for motorcycles four wheelers snowmobiles small engines etc

thingiverse

UPDATE: I've been using this for a couple weeks now with no problems at all. It works great, and I wish I had thought of it a long time ago. I'm adding the V2 version, which has a flat base that allows the key to print vertically without support. The base also improves the finger grip on the key, making it easier to handle. Prints faster now as well. The choke lever on my Kawasaki Vulcan kept sliding open, refusing to stay closed on its own. I designed this key to hold it closed while the engine warmed up, similar to other designs but with a unique twist - it snaps onto the choke rod and stays put. It should work for a variety of engines with similar choke design, as long as they have a 4-5mm diameter rod like mine does. The thin part of the key is only 2.5mm thick, essentially open to allow smooth movement. I could have made it thinner, but I didn't want it to be too fragile. The thicker part for the choke closed condition is 13.5mm thick, with a little ridge to keep it from sliding loose in the closed position. This design requires support to print, but I'm considering redesigning it with a flat base so it prints vertically with minimal or no support needed. So far, it seems to work well, and I'll be keeping an eye on how it holds up to the heat from the nearby engine head. I used PLA material for this project, which might not be the best choice in terms of durability. But it prints fast - under an hour at 0.1mm resolution - so that's a bonus. Let me know if you like it or want any changes.
