World's Fastest Can Opener

Have you ever thought to yourself, "Wow, I spend too much time opening cans"?

I have.

A manual can opener takes about 9 seconds to open a can of corn.

To solve this problem, I came up with a product that is guaranteed to save you tons of time. It's a simple adapter that connects a drill to your manual can opener handle.

Now instead of 9 seconds, you can do it in 0.3 seconds!

For comparison, here's how much time you'd spend opening cans (on average*) over 80 years:

1. Manual can opener (9 seconds): 83.2 hours
2. The World's Fastest Can Opener (0.3 seconds): 2.8 hours

*Estimate figures based on user opening 2 cans per day, 4 days per week. Adjust figures based on your usage.

Here's what I used to complete this project:

1. Can opener - https://amzn.to/41pVDCp
2. Screw - 4-40 - https://amzn.to/3Y1jVjf
3. Foam tape - https://amzn.to/3SzLDSY
4. 3D printer - https://amzn.to/3Zs5FBe
5. 3D printer filament - https://amzn.to/3zdndWt
6. Allen wrenches - https://amzn.to/3EVhlog
7. Corn - https://amzn.to/3YKrvzI

I designed an adapter to fit onto the handle of this can opener: https://amzn.to/41pVDCp

Print this bad boy on someone's 3d printer.

I machined an adapter shaft from aluminum. However, you could probably get away with 3d printing one.

The through hole is tapped #4-40 for the bolt that connects the adapter to the shaft.

I added foam tape on one side of the internal pocket that interfaces with the can opener handle. This just takes up a little space and helps grip the can opener twist handle.

1. Insert flat of shaft into mating feature on the adapter
2. Bolt shaft to adapter

It's time to get yourself some cans and test out your super speedy can opener!
