This tool can be used to make holes in leather, thin plywood, paper, cardboard - for short, in any soft and thin material you can imagine. The tool has a reservoir, that allows the user to make multiple holes in a row. The reservoir can be easily emptied and the piercing part cleaned, using a wooden rod.
To make holes in material, the user can either turn the tool, while applying force on it, or tap it with a rubber hammer.
Making this tool costs exactly 0 dollars, because it's made 100% out of an empty CO2 cartridge.
So, let's get started!
Here's what you need:
So, yeah, that's everything you need.
In my first prototypes, I used also a piece of copper pipe to make the cutting part, but I found the Idea of making a whole tool out of only one CO2 cartridge so much cooler.
