Friends don't let friends use 80/20. I've used exclusively https://us.misumi-ec.com/ https://us.misumi-ec.com/ for all my extrusion needs. They're one of the best companies I've ever worked with. Every order is a "custom order" - you tell them what you want including cutting, tapping, drilling.. You name it. Tolerances for a 20mmx20mm is 1mm cut. 15x15 tolerance is down to .5mm ! Their prices are also very reasonable, and shipping is good. I've also had a weird question about tolerance of a right-angle bracket, and their system imported the data wrong. Told that to the tier 1 support, and they went and found an engineer. Yeah, 5 minutes from calling to talking to the engineer responsible for that line. (Damn!) The only caveat is they can't easily calculate shipping the first time a package shows up in the area. But after 1 delivery to a zip code, they can accurately estimate it.
