spur gear collection 01 3D 打印模型

spur gear collection modeled in inventor 2010 and provided in multiple file formats. collection includes 7 spur gear sizes, all 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, allo***g 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.

gear specifications:
- approximate involute gear tooth profile
- minimal backlash ***ween gears
