Very useful print. I have shallow drawers and a lot of Gridfinity designs are too tall. The fact this had a shorter non-stacking option worked great for me. The only issue for me is the usual general Gridfinity issue that the magnet holes print like poop. There are some remix openscad bases out now that fix this, but Zach's original base models are horrible for gluing in magnets. This is after I picked out the spaghetti and tried cleaning out the space with a soldering iron. All but 2 magnets across the whole bottom failed to glue in.
I printed this on my A1 mini and the print quality is 5 out of 5! I ended up choosing the smaller since I wont be having more than two extra nozzles, so no need for stacking for my situation. The magnets fit perfectly and same going for the nozzles. Overall a very great print!
