Introduction: World's Fastest Can Opener
Have you ever thought to yourself, "Wow, I spend too much time opening cans"?
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:
- Manual can opener (9 seconds): 83.2 hours
- 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:
Step 1: Print This Adapter
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.
Step 2: Machine/print the Adapter Shaft
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.
Step 3: Add Foam Tape
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.

Step 4: Assemble
- Insert flat of shaft into mating feature on the adapter
- Bolt shaft to adapter
Step 5: Those Can Won't Open Themselves!
It's time to get yourself some cans and test out your super speedy can opener!
