Heart Shaped Box with LED
thingiverse
Human: 3D printed heart-shaped box with a red LED, simulating a heartbeat. The electronics comprise just an ATTINY45, CR2032 button battery, RED SMD5050 LED, push button, resistor, capacitor, and some wires. I adapted the original design by printing only the bottom part of the lid, then separately printed the lid holder and attached it to the push button. https://youtu.be/UsCT8t6KVLU https://youtu.be/aolZUn9VYpc Print Settings: Printer Brand: RepRap Printer: Prusa i3 Sunhokey Rafts: No Supports: No Resolution: 0.2 Infill: 50% + Post-Printing I opened the lid in the dark.
