After half a dozen iterations, this was the first reasonably working, acceptable feeling, and good-sounding ratchet mechanism.

allows clockwise rotation blocks counterclockwise rotation

design features:

  • allows for a large inner bore (e.g. rotary encoder shaft or 5.2mm screwdriver bit)
  • printable with 0.4mm nozzle
  • 2cm diameter
  • no assembly required. Print in place.

To get a full ratchet: mirror the assembly and add a mechanism/part that pushes one of the springs out. In neutral both leavers are engaged and the ratchet is completely locked.

Btw. Good luck copying it without going through half a dozen of iterations. Going from it barely works to this isn’t easy. For my part: Version 5 was working and close to the final design. It took another 10 rounds to get it usable and from there some more to fine-tune it.

    Then post the parametrised step file so people can tinker themselves.

    That said, if you did all this work and went through all these iterations to make a single ratchet that nobody else can copy then it sounds like you massively wasted your time. I would far prefer something with a tiny bit of assembly to a print-in-place gimmick that takes far more effort. The only way this makes any sense is if you’re making a lot of them.

    I guess keep it to yourself in that case.

      Watch your attitude.

      I think you still somehow assume this is some kind of ad to sell this design for money or I am a jerk for not just publishing it with source files.

      Also not everybody spends their time designing and publishing whatever is popular at the moment on Makerworld to collect points/store credit. There is a different world that doesn’t run on Fusion360 source file most people could edit and can design parts with a particular material & print(farm)/process in mind to get the most out of the FFF 3D-printing process.

        Lol, you got told your attitude was the problem and you just had to offload that onto me, didn’t you?
