prusaprinters

Instruction :I used a peace of binding wire ( usualy used for fences) D 2 mm1 blue LED ( the smalest i had lieing around ) D 5 mm L 10 mm2 Batteries ( the smalest i coud find to power the LED ) AG1 ( LR621) in series 1 smal swich i had at hand i printed the part in clear PETG super glued the wire in. And placed the other parts. The positive leg from the LED touches the positiv side of the top batterie. The batteries sit on top of each other ( +,-,+,- ). The ground leg of the LED is souldert to the swich and one smal wire goes from the swich to the negativ side of the lower batterie.After that i covered the top batterie, the switch and the canal on the outside with play-doh putty. So i wouldn't over paint them.I sprayed two layers of primer and pant on the part and removed the putty afterwarts . Now the LED shines only throw the canel outside.
