*Disclaimer: i have only had time to test print the small 1x3 rack so far. I had to fix the top to have larger holes to fit the bottom. If you have trouble let me know. I also fixed my old Solidworks files to be on the front plane rather than the top plane for 3d printing format.
I think the huge one can be printed on a 6"x6" print area on a Lulzbot mini but you would need to go into Cura advanced settings and disable the "skirt" feature to do so. Perhaps i will modify that one to be smaller yet in the future. Just been busy, and don't have filament right now.
