2015-11-09 (M) Miscellaneous 3D Printed Rack Gear COMPLETED

Another gear style which may become useful in the future is a rack gear. This linear gear could interface with gears previously designed and printed. As with previous models like this it is available as an OpenSCAD file so it can be viewed, modified, and exported by anyone for free.

Modeling started with the tooth module from the previously designed gears which skew a cube to make the diamond shape. Half of the diamond shape is visible while the other half is hidden inside the solid base. If the base is thin enough the backsides of the teeth can be seen through it. This is not demonstrated in the animation which shows the versatility of the rack gear.
