Plastic bottles cutter

Plastic bottle cutter- we all saw theese somewhere in one point, and now you can print one for yourself! Print flat and put piece of three connected scalpel knifes (non broken ones) into small empty square which is on around 8th mm from bottom. You need smaller scalpel, cannot use ordinary one, or use piece of razor blade. Empty space for knife is 0,45mm tall, so take that in mind and calculate according to your layer height. Inside there is small arrow, and if in that way goes rotation of bottle while it was cutted, you need to turn knife according to that direction.
Happy printing, and if you have any question, feel free to ask!
