Personal fabrication — a home shop extension of the same skills that live in my engineering work, without the engineering constraints.
Making is what happens when you have a problem at home and the answer is: design it, print it, install it. A home printer changes your relationship to the physical world — you stop accepting that the part you need doesn't exist and start treating it as a design problem you can solve in an afternoon.
My personal printer gets consistent use. Projects range from purely functional (cable management, brackets, replacement clips, ergonomic accessories) to creative (custom enclosures, props, display pieces). The constraint of "it has to actually work, not just look good" keeps personal projects honest and forces real design thinking even outside of work.
I design most personal prints in SolidWorks before slicing — the same workflow as professional work, just without the documentation overhead. Sometimes I modify or remix existing designs from print communities when the geometry is already close to what I need.
Adjacent to printing: electronics, Raspberry Pi projects, 3D printer maintenance and tuning. I've worked through a printer build/upgrade cycle — adjusting bed leveling, PID tuning, first-layer calibration, and firmware updates. Understanding the machine well enough to fix it is part of the hobby.
"The best thing about a home printer is that failure is cheap. You can print something that doesn't work, understand why, and have a better version running by the next morning."
