Here in La I believe Lowes and hd both carry wheatland. at least for now. I got mine at hd and it is still grinding zinc off on a daily basis. but it’s got much better after I let it go with the box print for a while. i did it because I noticed that about 15mm from home I would see and hear a slight rub and grab. which would totally mess things up if I had to do a filament change mid-print. now they’re smooth as silk.
