"Desk Accessory" CNC Milling Machine

Trying something(s) different here:

• different layout for more compact footprint
• 3d printed parts instead of laser cut parts
• longer and now cheaper generic flavor of motor+screw unit for larger work area

It's still work in progress, but seems like it might work out ok.

The mechanics are a lot like #Minamil: a minimal CNC mill. And friends., but different. Re-design for 3d printing the mechanical parts is not just trivially different from design for 2d laser cut parts. I don't know yet whether to expand that project or start a new project.

For evidence of progress beyond CAD and hand-waving, here's a three minute video:

Being distracted while not doing something else...

...I think I've figured out how to make the compact corner/angle configuration stiff without just making it bigger.
