3D Printing
The printer earns its keep on knick-knacks and functional household items, but it's also just an ongoing hobby in its own right - calibration and bed leveling included, since keeping a printer dialed in is as much a part of this as any individual print.
The build I'm proudest of started when my son got into dinosaurs: a full T-rex skeleton, printed piece by piece - skull, spine, ribs, legs - and assembled on a display base. It's the same model used in some actual museum displays.
Not everything is an original design. Plenty of prints are STLs I downloaded and just ran - articulated, flexible dragons and creatures that print fully hinged in one go, no assembly required, and a Jurassic Park raptor claw. I also printed a miniature replica of a wooden playhouse from the kids' childhood - the real one was bought, not built, but the mini version is one I made as a keepsake after it was gone.
Some prints cross over into other hobbies entirely: I built a 3D printed LED light box - CAD design, LED wiring, an ESP32 running WLED - to house a laser-cut cube portrait of my dad and my son. And when I upgraded the speakers on a Batocera retro-gaming build, I printed a custom enclosure to house the new speaker rather than buying one off the shelf.
