Hi makers!

This is a functional and printable design that locks on top of most traditional cans.

It has been designed to work in junction with a RTC Arduino and a hobby micro-servo.

When you set a specific time frame in the Arduino sketch, the servo actuates the wheel to lock the can accordingly to the hours.

For example, you could only drink beer from 7pm to 9 pm!

Supplies

M2.5 bolts and nuts

PLA filament

3D printer

Step 1: The Prototype

The printed parts fit perfectly on standard size cans and it has a good grip.

This could be a good starting point or an inspiration for more complex drinks-free projects!
