Had a re-think on my turn signal stalk extender after the first version of it broke because I really hadn't thought the design or printing considerations out very well. The new version comes in two parts that fit together with an M6 screw and nut. Throw a little bit of FunFoam in as liner for the stalk ring clamp and it's pretty solid.
The WHY: When installing a deep-dish wheel on-top of a quick release hub the wheel is moved away from the turn signal stalk. This make it a very annoying stretch to reach the stalk to do what the stalk is meant to do while driving the car. This paddle/stalk extender helps to reduce that issue.
Originally I'd bought a part off of Amazon to just this very thing. It was a cheaply machined piece bit of aluminum that looks pretty heinous and only sorta kinda works alright. The most significant issue with it, apart from being FUGLY is that it's 3.5oz. That extra weight would sometimes cause the stalk to fall jump out of position if the car hit a bump.
This version, printed in PLA with layer height of .24, three shells and 25% infill clocks in at just shy of .5oz. Significantly better.
For grins and giggles I've included the Fusion360 file in the upload.
I've added a longer lever arm to the mix however I have not updated the f3d file for it.
