Introduction: Can Lock
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!

I don't get it. Where is the servo?

It reminds me of a hatch mechanism on submarine .you aren't ex Navy by chance ?

Nothing like that...but I love mechanisms and I watch documentaries, maybe I designed something similar to what I saw without realising it :)

Like me, you are open to being inspired by things around you. I believe that to be very important. Good luck going forward.

Neat! Do you have a video of it locking and unlocking?

No sorry...at the time I didn't plan to make an Instructables :) but I will try to find the assembly file and make an animation!

Clever idea! Will you be adding the print files, and perhaps some explanation of assembly? That would be very helpful for anyone wanting to make this! : )

Thanks! Unfortunately I can't post the files because I originally made them for a company :/ but the design is not too complex! in the two renders I posted you can see with and without the wheel that moves the mechanism...I wanted to give an idea of how I made it....and talking about the assembly, I only used some hobby M2.5 bolts!
