Laser cutter/engraver. Can do a whole class worth of projects in less than 20 minutes, FAST and cheap fabrication, can also make projects that can be sold in fundraisers…to further help buy more stuff for your space!

That depends on how much money you’re talking. If you have bare minimum (less than $100), get as much cardboard and cardboard cutting tools as you can, as well as The Extraordinaires Design Studio. If you have $20,000, get a laser cutter/engraver.
