Have a look at what xTool is offering with AI integrated design tools where you can put in a prompt for a design, have it LLM AI enhanced, edit it, then have a visual AI create a design that you can have CNC lasercut with the Metalfab and then you weld together with the laser welder.
Extraordinary stuff. You don't even need to be "creative" in the artsy way, just have an idea about what you want.

It is already possible with 3D printing (incl tough resin SLA), this sort of home laser CNC machine & a regular CNC machine to create almost any product, including unique engineering solutions, that you might ever want.
Its just a matter of finding the off the shelf standard bits on Ali Express etc and then creating parts to link them together to do what you want. With Open Source the electronics and software can be endlessly adapted.

In my experience, once you get outside of mainstream products and into specialised areas it is often cheaper to design & build your own bespoke product that meets your specific needs than to buy something off the shelf.

In specialised physical product areas prices are vastly more than actual production costs because there is such regulatory overload and marketing is very expensive low volumes.
