Old door locks rank high among my favorite bits of obtanium: not only do they make great bases, but their innards provide all sorts of possibilities.
The extent of today's tinkering: needed a paper towel holder in the shed so I threw together a paper towel holder for the shed. Is it pretty? No. Does it hold paper towels? Yes. Success.
Scanned the bones of yesterday’s big yard piece and 3d-printed a tiny version so I can fiddle about with it inside The Shed with paper and cardboard before fully committing to each component of whatever this thing ends up being.
