Precision Gears [ Addon ]

TLDR read the bold text.

Precision Gears is a blender addon developed to bring an array of mathematically accurate involute gears to the precision world of Blender. Not only that, it's all incapsulated inside the closest thing to a faux "parametric" system, giving you the ability to change your gears on the fly. Also, integrated is a gear rigging system to create parametric gear chains that are animated.

Minimum version: Blender 3.5

- PLEASE NOTE -

Technically Precision Gears is forever evolving and in a state of open "beta". Gears are a very complicated topic to understand, teach and develop for, so be patient a whole bunch of videos and a wiki are planned for eventually. In the time being if you find any consistent bugs that you are able to replicate or have any future development ideas I would love to hear from you. The best place is in the maker tales discord in the Precision Gears channel link: HERE. Alternatively, you can fill in this form: Here not reviewed as often.

If you would like to test out a reduced feature "lite" version to evaluate how the addon works it's linked: here.

The addon is available for download for $8. With that said it would be greatly appreciated if you have the means to pay the suggested $15 or more as this will facilitate further development of this addon along with other precision addons for blender.
