Sho(r)t Timer Housing

thingiverse

To continue my blue/green espresso accessories series, I've made a timer for my coffee grinder. After 30 years of electronics tinkering and acquiring a 3D printer, I designed a housing for a 5x10 cm PCB with wire inlets and screw columns to stabilize the walls. The lid features the main switch, potentiometer, push button, and illuminated frames for 5mm LEDs from below. For the electronics and wiring, refer to countless NE555 circuits online. Attached are source files for inspiration, but note that switch hole sizes may vary. Print items with support for knob holes, use transparent PLA for displays, and drill slightly larger holes as needed. Fix the lid with 3x M3x25 mm screws and tapped columns, hide screw holes under the knob for better WAF (Woman Acceptance Factor). Secure mains wires with cable ties inside the housing. Happy soldering and printing!
