I can't wait for parts direct to get a new shipment, I just need a link to something I can order from Amazon, plug it into the R2 I've been saddled with at work, and have it start printing. I can't keep spending my own money (I'm a teacher) on parts HOPING that they'll fit. I also don't have the time, energy, or interest in 3D printing to do any more fruitless research on which parts are compatible with which machines. And now I have to spend my Friday night in my classroom trying to fix our R1+. Thanks in advance.
