A selection of valentine’s day STL files. These minis are designed to be printed at 28mm scale (this is the current scale of the STL files) and will take a 2025 or 2032 button battery with a 3mm LED in order to make them light up. Once the battery and LED are in place the minis will glow and can be turned off by either sliding a piece of paper just above the battery and under the wire. If the cathode protrudes it can be slide into the groove on the top of the insert. Most batteries will stay near full brightness for a few days.
