Modular shelf, with guardrails

I wanted a shelf to put our laundry soap on, as it allows us to set the cup under it while we fill it. However, my printer wasn't big enough to print a single shelf all in one print. So, I did a quick design to create a "small" table that could be bound together. I also wanted some walls on it to help hold the soap container.

Theoretically, you could print as many of these as you wanted and clip them together to make a much larger raised platform. There's really no limit to the overall size.

I printed these with 1.2mm walls and top/bottom, with minimal infill so it's pretty strong, as-is.

You need one 'clip' for each set of 4 that needs to be bound together. Simple superglue would make the clip permanent, or you can just slide it on and later be able to slide it off.
