Stepper Bracket Factory (Type 1/2)

Fully parametric motor mount bracket in L-shape with triangular reinforcements. The original parameters make this suitable for a NEMA23 stepper motor, but you can adapt them all.

Available parameters:

* width
* fplate_height
* fplate_thickness
* fplate_between_holes
* fplate_screw_clearance
* fplate_cbore_diameter
* fplate_cbore_depth
* main_bore_diameter
* main_cbore_diameter
* main_cbore_depth
* bplate_length
* bplate_thickness
* bplate_between_holes
* bplate_holes_offset
* bplate_screw_clearance
* bplate_cbore_diameter
* bplate_cbore_depth
* gusset_thickness
* gusset

This design is based on Edi Liberato's "[Parametric Stepper Motor Bracket](https://eddieliberato.github.io/blog/2020-08-01-stepper-motor-bracket/)". Kudos to him for providing some of the very few CadQuery designs available online.

The CAD model was made using [CadQuery](https://cadquery.readthedocs.io/), an open source CAD software similar to OpenSCAD (but much more powerful). The latest v
