Worm Drive Gears Redux

thingiverse

This is AdditiveTech's excellent Worm Drive Gear, [Thing 2144347](http://www.thingiverse.com/thing:2144347), but with flaws in the STL files corrected. The usual flipped normals and other errors produced by software such as Sketchup have been fixed. It now works correctly with most slicers. As per [Thing 2144347](http://www.thingiverse.com/thing:2144347), this is a 30:1 worm drive reduction gear in three separate parts. The worm wheel has a helical design. https://youtu.be/VE7kmcveCOQ It's best to print the crank/screw standing upright with supports touching the build plate. Be cautious when removing the crank from the build plate; the orientation of the layers makes it easy to break it off, leaving the base still attached to the build plate. Printing at a layer height of 0.2 mm may result in a sturdier part compared to printing at a layer height of 0.3 mm.
