After the print is complete the top layers of the board should have 3mm+ conductive filament.

Pin 2 and 6 are connected. All other pin connections will need to be made manually.

Place 555 timer onto 3D printed board and press firmly to make a strong connection. Careful not to bend the legs!

1. Connect pin 4 and 8 together with a male to male jumper or wire. *tinned wire for optimization

2. Connect LED ground leg to pin one.

3. Connect R3 (1K ohm) to +itive lead of LED, and then to pin 3.

4. Connect R1 between pin 6 and 7

5. Connect R2 between pin 7 and 8

6. Place C1 between pin 1 and 2 *-itive lead to pin 1 (for polarized capacitors)

7. Note: Pin 5 will not be connected (this is also called floating)

The last step is to power the circuit. 5V-9V is a good value to use for the power supply. Here I used a 9V battery and snap connector.

Connect negative lead to pin 1. Connect positive lead to pin 8
