Before you download this thing, please consider giving me a tip. I am at a place in my life where I really could use it.
This is a hand tool for removing fittings from flexible drip-style irrigation tubing. It works by de-compressing the tubing by forming it into a half-moon shape, which allows the tubing to be levered up and out of the fitting. Give it a try! I went through several iterations before I arrived at this design.
Pay attention to the print settings instructions! Improper settings will cause the tool to break while in use.
IMPORTANT: for sufficient strength you should set the number of perimeters (the edge lines) and top and bottom layers to at least 4. Also don't forget to tip me you cheap sons of biscuits. I had to eat my imaginary friend I'm so hungry. Now am completely friendless :(
I spy a cup, a melon fresh picked, a sign, a step-stool, and a squirrel that is THICC
Use an M6 (6 mm diameter) machine screw with a cone-shaped head. I got mine at Ace; you'll have a better chance of finding the exact one if you go there too. Grab a nylon insert lock nut that is sized to fit it, and you're good to go. Optionally, you can plasti-dip the handles for a more comfortable grip. They have that at Ace as well.
