Miata Turn Signal Stalk Extender Mk.II

thingiverse

I had a major rethink on my turn signal stalk extender after the first version broke because I hadn't thought through the design or printing considerations at all. The new version comes in two parts that fit together with an M6 screw and nut, and adding a bit of FunFoam as liner for the stalk ring clamp makes it incredibly solid. The reason behind this project is to solve a major issue: when installing a deep-dish wheel on top of a quick release hub, the wheel moves away from the turn signal stalk, making it a very annoying stretch to reach the stalk while driving. This extender helps reduce that problem. Originally, I bought a part from Amazon specifically for this purpose, but it was a cheaply machined piece of aluminum that looked ugly and only somewhat worked well. The main issue with it apart from its appearance is that it weighed 3.5 oz, which sometimes caused the stalk to fall out of position if the car hit a bump. This version, printed in PLA with a layer height of .24, three shells, and 25% infill, clocks in at just shy of .5 oz, significantly better than the original. For kicks, I've included the Fusion360 file in the upload. I've also added a longer lever arm to the mix, but I haven't updated the f3d file yet.
