Fully parametric herringbone gears for Wade extruders

thingiverse

This code contains links to a collection of STL files hosted on Thingiverse, a platform for 3D model sharing. The files appear to be custom-designed gears with varying decorations. Here's an explanation of what each section is trying to accomplish and how the STL file links relate to those accomplishments: - `herringbonegears_shaft_5mm_hobdistance_9p5_ratio_9to47_distance_39_decoration_foursegments.stl` - A gear with a shaft diameter of 5mm, hob distance (the distance between the end of the shaft and where it is attached to the wheel's hub) of 9.5mm, ratio of teeth on the input pinion gear (driving gear) and output wheel (driven gear) equal to 47/9, a total width or diameter equal to 39, and decorated with four segments. - `herringbonegears_shaft_5mm_hobdistance_9p5_ratio_9to47_distance_39_decoration_spiral1.stl` - Same setup as before, but with decoration set to "spiral1", meaning that instead of or in addition to the segments (in this case likely rings) at a regular pitch, each segment was replaced by spiraling tooth cut-out. - And so on... - Most items have either `39` and then different types decorations such as: \[Solid - with no decoration but solid fill inside. \] - or: \['Foursegments'\ 'twosegments' or whatever variation on a common 5 design is made for it \]
