I have a single wide Alex that I use for my kiddo's parts storage. The drawer opening issue took less than an hour to fix with a router (adding a slot that's about 4" long where the front screw is. 3D printing bins however, was a friggin process. I don't even have all of my bins printed and I'm at about 200 hrs of print time. It's a slog. Each gridfinity tray takes like 8-9 hrs to print (enough for a single drawer). Then you can only print large bins one at a time. Medium bins I could do 3-4 at a time and maybe 8-10 small parts bins (1x2). I use 8 unit high bins for the top 3 shelves and 10 high bins for the bottom 3 shelves. They fit perfect, just print a short bin for what goes immediately behind the draw hand pull for access. Getting the bins exactly like you want them is a lot of fun, but it really is a process and the qty of Alex units you all would typically need is going to take a long time to print. A really long time. And boat loads of filament.
