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.

Minimum version: Blender 2.92

- PLEASE NOTE -

This is a "beta" release some pretty big & exciting changes will be coming to the addon in the next coming months. Plus a whole bunch of videos and a wiki 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.

I'm currently developing the gear "presets" if you have any ideas of how I should standardize these I would love to know your thoughts.

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

Getting this addon for $24 on blender markets rather than gumroad at a cheaper rate is greatly appreciated as this will facilitate further development of this addon along with other precision addons for blender along with supporting blender at the same time.
