Gearbox Asset Reference
This asset library contains a collection of geometry nodes that generate mathematically accurate gears and gear-related items. My goals were to,
Challenge my math skills
Improve my geometry node skills
Generate gears that have a chance of working properly if printed
Create meshes that are topologically sound
Changes in V2.0
Uses Blender 4.3 release candidate.
Added straight bevel gears.
Added a gear rack node.
Added a beveled shaft
Reworked the cog mesh to allow better smoothing.
The clearance value was moved to an internal constant value.
The pressure angle is constrained to a reasonable range. Several other invalid input values may give error messages.
Categorized many node inputs into panels where appropriate.
Added a Working Notes section in an attempt to keep the math organized.
Added a Modeling Tips section to improve usability.
