Customizable hole punch

thingiverse

A customizable hole punch. Given 3D printing mostly happens with plastics, i think it's only usable for paper or cardboard. But you can try it on anything of course (except on your little brother). The tip is exactly the diameter as specified at the customizer input, from that point up it immediately increases in diameter to 2mm larger than the punch diameter, so the waste won't be stuck inside it. Small how-to-use: - Use something underneath the workpiece like scrap wood or a cutting board from the kitchen. - Hold the punch on top of the workpiece where the hole needs to be. - Wack it with a hammer. - For any injuries; blame anything except me :D. Though if you have any safety improvement ideas feel free to suggest it. I do take safety seriously as we all want to go to bed in the evening with the same amount of fingers as we got out in the morning. Though i cannot make guarantees on how fast I'll have processed improvement ideas. At this point it's still untested so not sure if it works. I'll be printing it in a moment. Edit: The hole comes out a bit larger after using the tool, than than the diameter specified in the customizer. I think i'll leave this project for a bit.
