Java Random Structure Generator Help

Hello, I'm looking for some up to date help with a random structure generator in minecraft java 1.14 as a datapack. I know of Tyruswoo, but I want to make my own random structure generator with structures that I have built. I was wondering if there were any other resources out there that might help me, or if someone else has an up-to-date structure generator datapack I might be able to borrow. Thanks.

Cheers!
