I tried parametric design and published a set of heart-decorated 3D-print boxes in 500 sizes (35–120 mm). I explain part numbering, two lid fits, and printing tips, and I've shared the STLs on GitHub. Read the full post to find the exact size and download files for your printer.

I wanted my winter decoration to switch on at dusk without constant adjustments, so I built a simple low-voltage controller using a P-channel MOSFET, a microcontroller and an ambient light sensor. I walk through my design choices, sealing for outdoor use and programming tips—read on if you'd like to build one too.
