Today, while thrift-shopping, I found an important component for our satellite building.

Yes, it's a rolling trunk, and I'll admit it's not the most exciting science prop. But there are four important details that make this an important detail in DIY satellite building.
1) Pragmatics. I need a place to store the satellite and components when I'm not working on it.
2) Conveyance. I need something to lug the kit around when I take it over to my friend's workshop, when we eventually get to final assembly.
