Plastic Bottle Cutter

thingiverse

I saw the Plastic Bottle Cutter Kickstarter and their website at https://plasticbottlecutter.com/. You can take any plastic bottle and make cordage out of it. This is useful when you're out of civilization and need cordage. 10 loops from a 2-liter bottle can tow a car. It's also a great way to reuse plastic soda bottles. If you make the strips thin enough, you can weave them into multi-strand rope or a belt or fabric. With heat from a heat gun, it shrinks to fit any surface exactly. You can make plastic handle protectors for all your tools by wrapping the plastic cordage around the handle and hitting it with the heat gun for a few seconds. But $50 (US) for shipping one of them to me wasn't really economical. So I modeled it in Tinkercad and printed it out on the Zortrax printer we have in the shop at https://www.tinkercad.com/things/43nrR97T5VQ-plastic-bottle-cutter/editv2?sharecode=5iGMymW9r71yHxGpc7c_yf6E1O2qkjvKbm3xAu2weOs=. The center is meant to be held upright, and the horizontal slot is for a piece of a 9mm snap-off blade. The slider then slides onto the center piece. The hole in the back is meant for an M5 thumb screw. My intention is to thread the hole with a tap. Additional materials you'll want include: 1. A 9mm snap-off knife blade, which can be found at every hardware and craft store as well as Walmart. 2. An M5 thumb screw, which I think can be found at that hardware store named after a playing card, but I ordered mine online from eBay. I've tested this, and it's working pretty well so far. I don't have the thumb screw in yet; I need to get to the hardware store for that.
