I loved the original, but wanted to make a version that easily stacked (for when you get "kinged"). There is about 3/4" of a bridge that is needed. I think most printers can handle that, but if your printer is bad at bridging, this may be tricky for you.

I modified these in TinkerCAD, here is the link if you want to edit them some more.
