ok firing up the printing just a quick question on hardware

So on the BOM I noticed a listing for metric bolts and imperial bolts. Do you have to use imperial on the non international edition? Debating sourcing my own parts or just buying a kit. I am looking to build an usable 24inch sqaure area so looking at maybe a 36in frame. I think that is the maximum for not needing additional support.

They should be roughly equivalent. Use either ones on either kit.
