Mechanical Parts Library

thingiverse

Mechanical Parts Library currently contains three projects: Gear, Rack, and Wheel. Each part has many customization options. The library will be expanded in the future with more parts. Comments explain modules, parameters, and code. I welcome suggestions on what to include next. A customizer is available for gears at http://www.thingiverse.com/thing:1427458. This library is licensed under the MIT license, but since it's not listed here, I've chosen LGPL (compatible with MIT) from the list. Any parts you create with this script are your own work and can be used as desired. Features: Gear: Spur, helix, and double helix gears Customizable pressure angle Cutoff for gears with 5 teeth possible even at a pressure angle of 0 Uses metric units Semi-gears with reinforcing Multiple mounting hole shapes and features Different spacers to reduce material use: polar for equal angular spacing, circles for circular spacing, linear for equal distance spacing, polar ovals for nice-looking spacers Adjustable details Single polygon gear generation algorithm for fast rendering Rack: Spur, helix, and double helix tooth Customizable pressure angle Uses metric units Single polygon gear generation algorithm for fast rendering Adjustable rails for top and bottom Wheel: Multiple mounting hole shapes and features Different spacers to reduce material use: polar for equal angular spacing, circles for circular spacing, linear for equal distance spacing, polar ovals for nice-looking spacers Adjustable details Chamfered or straight wheel with a method to reduce or remove overhangs Ability to create bridgeable arms Customizable/optional tracks (only one style available) To Do: Joints Bevel gears with octoid profile Worm gears Hinge Spiral & hex spacer Propeller Hand crank Pulley Timing belt Z-axis spacer for wheels
