Plastic bottles cutter

thingiverse

We've all seen those plastic bottle cutters before, and now you can print one for yourself. To do this, simply print the design flat and insert three connected scalpel knives - none of which should be broken - into a small empty square located approximately 8mm from the bottom. Note that you'll need to use a smaller scalpel or a piece of razor blade, as an ordinary knife won't fit in this space. The empty slot is only 0.45mm tall, so make sure to factor in your layer height when printing. Inside the design, there's a small arrow indicating the direction of rotation for the bottle during cutting; be sure to orient the knives accordingly. When working with sharp objects, always use protective gloves to avoid injury. If you have any questions or concerns, feel free to ask!
