2.5" to 1" Drain Pipe Reducer

thingiverse

I've got a 2.5" hole in my slab for my A/C drain pipe, but the drain pipe itself is only 1". So this sits in the slab, can't fall all the way down in, and lets the 1" pipe connect to it. Print it out of anything you want, I'd recommend PETG or ABS if it's going outside. Print it small side down with a raft and don't use support, or print it large side down with support.
