Grumpkin 2: candy box, secret lock, glowing LED eye

thingiverse

The third photograph displays the inner components, including the battery cover and small switch, wiring, and dental bands for the lock spring. The fifth picture offers a detailed breakdown of the printed elements. All pictured prints were created using a Form1 printer with grey resin for the body and clear resin for the glowing eye/secret lock. To assemble the "insert" part, attach a battery cover designed for four button cells by screwing it onto the main body with an m3 machine screw and nut. You will need to create a foil bridge to connect the cells and solder in wires and a switch, which can be seen on the right side of the base in the third image. The switch used is from an old mouse. A notable enhancement would involve connecting the switch to the eye hinge/lock instead.
