Precision Gears Lite [ Addon ]

26 ratings

TLDR read the bold text.

This is the Free feature reduced version of Precision Gears 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


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

To get all the features that are listed below head on other to the full version of the addon linked: HERE.
