The "Mostly-Printed CNC" machine (MPCNC Primo Edition), is a budget, DIY CNC router, made from 2kg of 3D printed parts and 20 ft of steel tubing/conduit. Initial cost was about $600. Will be spending more on dust collection, cable guides, enclosure, etc.
I have NO AFFILIATION with the MPCNC project or V1 Engineering, I was simply intrigued by the strange design and was pleasantly surprised by the result!

I created a spreadsheet with a cost breakdown and links to where I bought stuff. If you're interested to build one yourself, check out the V1E links above, and consider buying a kit from them instead of sourcing individual components. Technically you can get everything from the V1E shop except for the steel conduit/tubes.

Finally, here are a couple things I designed for this project:
* Print-in-place folding electronics enclosure for Jackpot CNC controller: https://www.printables.com/model/682484-mpcnc-foldable-jackpot-enclosure-box
* Adapters for full size limit switches: https://www.printables.com/model/682569-mpcnc-full-size-endstop-adapter
