Automatic Hand Sanitizer Using 3d Printer

Dear all ,

This is a very simple automatic hand sanitizer and by using 3d printing i am making the cover and nozzle which gives it a professional look.

This is the smallest DIY for hand sanitizer.

1. Ir sensor
2. tip31c
3. waterpump
4. usb wire
5. pipe
6. 3d printed case and nozzle.

We just need to connect the circuit as per the diagram .

3d printed files are added ,just download and print it.
