My awesome dad created this goal using wooden dowels, screw eyes, and rubber bands. We still have to add the nets, but this goal costed around $15.
That’s really smart. Your dad is indeed awesome! Home Depot here we come. 
Thanks for posting this.
Wow, this is really good! I was planning to build one out of PVC pipe, but this seems much better.
So what material is the official net made of? I may as well head to home depot too XD.
