About this 3D model
I liked the original's simplicity; But I wanted the freedom of anyone being able to make it as extended as their personal needs required . Everyone's Tupperware varies so crazily, it makes it difficult to choose one of these things to print. I get that. That's why I worked on this one. I printed mine pegs in the air direction (as you'll note in the 3MF file). This way, your tolerances can be nice and tight. I found 0.2 hole tolerance perfect for pushing it together, but not easily coming apart. Tighter than this required light hammer taps, which I didn't want to require. There's an extender as well if you're looking to expand the width between tall walls. ? Can't wait to see what people make (or add, if you're feeling creative and want to remix / contribute!)
