    Reproduction mirror switch project

    Hi everybody,

    I'm currently running a reproduction mirror switch project and decided to share it with the community since I guess at least some of you may find it interesting. The switch will be totally redesigned inside, using as many standard components as possible. The goal is to make it more reliable and user-friendly while keeping external appearance as close as possible to original. An optional LED backlit decal is also being considered. MJF or SLS technology will be used to manufacture all custom mechanical parts of polyamide.

    If everything goes well with design and prototype testing, a short pre-production series should be available by the end of 2019. The price of final version is estimated to fall between $160 and $200, assuming 20pcs minimum production run.

    As for the progress, an early pre-prototype has already been FDM 3D-printed, just to check some initial design ideas and general appearance:

    At the moment, mechanical design of 2 different prototypes is almost ready and MJF 3D-printed parts will be ordered soon:

    I'll keep posting updates as project advances.

    This is a great idea! I just wish 3D-printed stuff didn't look so "layered."

    Is just the prototype 3d printed to check the design? The production part will be molded?

    Final parts (and the two soon coming prototypes) will also be 3D-printed, but in totally different technology than the FDM pre-proto part. Surface finish will be like on the sample close-up attached below or even better, depending on post-processing method used:

    So this won't be using the steel ball/spring setup as originals did internally? It's a shame, I just rebuilt mine but could do with an upgrade as it is still a bit finicky.

    Great project! Will the internals be compatible with original shells? That would be helpful for repairing broken originals.

    Agreed... It would be awesome if the internals were replaced with micro switches. Of course I have no idea how to do that so...
