plastic bottle cutter

i based this from youtube design. https://www.youtube.com/watch?v=JMbT4DOi21U

the cap that holds the blade in also snaps closed to keep cap on securely.

i made slots for the blade in 1/8 increments, ranging from 1/8 to 1 inch.

i included a step file in case you want to make changes and personalize it in any way.
