assorted gear collection modeled in inventor 2010 and provided in multiple file formats. collection includes multiple spur gear sizes, multiple planetary ring gear sizes, bevel gears, worms, and racks (see below for more detail). all gears are ready for 3d printing.

the native inventor files are fully parametric and can be opened and manipulated in any version of the software that is 2010 or newer. the feature trees and parameter tables are logically arranged and clearly labeled, making edits a breeze. all gears have been exported as stp files, allowing them to be opened in any 3d cad software and many 3d graphics applications. all gears have also been exported as stl files, making them ready for 3d printing.

strategic recesses have been engineered into the larger gears to reduce their volume and thus reduce the cost of 3d printing.

as a bonus, planetary gear assembly animations are included as well!
