I liked the idea but wanted to use less filament, provide a way to pull it out if needed, and include a chamfer to the bottom side (if you wanted to print it that way)…

Please excuse any rough spots, I spent far too long trying to make it in tinkercad, then really showed how little I know but trying Fusion 360.. but it did have a chamfer button :)

note: I was using a .6 nozzle, but I assume not much different other than taking a bit longer for .4 sizes.
