Parametric, low-complexity fabrication linear axis designs using ubiquitous hardware.
## Gantry for NEMA23 Motor, 1/4" Aluminum

[RCTN23-025ALU Fusion CAD File](cad/RCTN23-025ALU_v49.f3d)
In Fusion[^2], you can open this file up and use (from the top menu)
``` Modify >> Change Paremeters ```
Each of these models should have some parameters *starred*, these are what you'll want to configure. Go ahead and set axis lengths, material thicknesses according to what you're doing. When you're satisfied, you can export the model as a .step file, using the file menu, to prep it for fabrication.
``` File >> Export ```
Make sure to change 'type' to .step, and check the 'save to my computer' box.

# Jake's Notes
- doc
- bom
- hardware callout drawing (probably more useful than video)
- nice to include a note on what those flexures are up to ... and some other design decisions
- kinematic mounts are three button head cap screws on 20mm grid w/ reciprocal / wherever-u-like mount ins
- all axis have scroll-along top plate w/ connection to motor plate, final scroll kinematic triangle
- all axis have scroll-along bottom beam plate w/ 20mm grid w/ last scroll kinematic triangles
