The kids received an early present of these cheap plastic sticks and balls with holes in them. When combined, you're supposed to add blankets, so they instantly become forts. I don't have an issue with this product at all, but the box of cheap, plastic crap is ~$40. What a rip-off!

So I decided to make one of my own that's infinitely expandable, sturdier, customizable, bigger, and significantly less expensive. The printer is in the middle of making my alpha version, but in two hours I'll be able to stick a 3/8" wooden dowel in there and test if the concept works. If it does, I'm sharing it on Thingiverse for all to use, so they can save that $40 entry fee bullshit.
