    tricky! 1, select the external gear option. 2, Adjust the helix. 3, teeth will be the number of paragraphs 4, Gear helix is ​​the length of the worm

    Have you got the solution?

    I just want a Gear with 42 teeth and a diameter of 35mm .... no option to do so

    Nico Schlüter (Publisher) | February 28, 2023

    Hello, thank you for your feedback. I am a bit confused what the purpose of this feature would be, as mating gears need to be of the same module to work together, and creating gears by number of teeth and diameter would create gears of non-standard module, you would need to do quite a bit of math to ensure two gears created this way could mesh. As a workaround for your problem it is quite simple to generate a gear of specific pitch diameter and number of teeth. Simply divide the number of teeth by the desired pitch diameter to get the module. 42 / 35 = 0.83333333 So a gear with a module of 0.83333333mm and 42 teeth would have a pitch diameter of 35mm For feature requests I would recommend opening an issue on the GitHub page. Hope this helps!

    What's the problem with putting 42 teeth and 0.8 module and getting a pinion with an outside diameter of 35.2? Maybe you just don't want to figure out how to do it?

    Evan Barnes | April 05, 2023

    Gear diameter is determined by things like the number of teeth and the module or pitch. You can't really precisely control the external diameter of a gear, unless you want to do some complex working backward from diameter to calculate the required pitch or module, and even then, you'd probably only get sort of close to 35mm diameter.

    fatto! modulo 0.79545; diametro 35mm; z=42

  • Best gear plugin I've used

    I could use this really easily, but works great

  • Works great. Non-parametric
    Ehjones Ehjones | December 07, 2022 Verified Download (What's this?)

    This is more flexible than the gear script included with F360. It's not parametric. It'll pick up user parameters when you first create a gear, but if you edit the parameter the gear will not update.

    When you mouse-over the tooth-count and helix-angle you'll get a hint on how to do worm gears - you need a high angle and a tooth count of 1 or 2.

  • Good!
    Alexander Neskazhu | September 02, 2022 Verified Download (What's this?)

    Отличный плагин! Включает в себя все необходимое, внешние и внутренние шестерни, прямл и косозубые, реёки. И при этом все корректно работает.

  • Great tool with a slight improvement
    Robert Mock | December 20, 2021 Verified Download (What's this?)

    I like this tool but like many others it dumps the gear into the root directory. I was able to change that on other tools and this tool too by replacing rootComponent with active Component in the Python code. It seems to be working fine with this addon and maybe that is something you will want to add to a new version as standart. Thanks

  • Thank you

    Nice and usefull

  • Looks great! Can we please have a "root fillet radius" setting?
    Arjun M | November 11, 2021 Verified Download (What's this?)

    Thanks for creating this!

    Can we please have a "root fillet radius" option? Same as how the regular "Spur Gear" sample add in does.


  • Nice plugin
    Mihaita Nastase | July 29, 2021 Verified Download (What's this?)

    It's a great plugin for small projects, it would be nice if you could work with parameters so you could edit the gears later on.

    William Donnelly | August 10, 2021

    Yes this would be extremely useful and I don't know why this functionality is not standard X)
