Pipe strap
I have to install an icemaker today. I need a couple of pipe straps, but it's early, I haven't finished my coffee, and I'm not even out of my bathrobe, yet.
Twenty minutes for design, thirty minutes to print two straps, and I saved myself an hour and a half trip to the hardware store.
Look out, Home Depot! The makers arise! Now, if I could just print some Teflon tape...
Scale as necessary for your project.
