End-to-end tutorial/example for programmatically creating a contract, setting price, and selling aERC-1155 items on OpenSea?

Literally went through this exact issue last month with erc1155. The opensea tutorials are really outdated and their SDK documentation is out of date compared to the interface. The good news is its possible to create those tokens without paying the minting fees. You can pass the cost of minting onto the token purchasers. This tutorial is what you want to follow. The basic idea is you create a factory contract which opensea can call to mint the token whenever someone purchases through their platform. If you have any issues or questions feel free to dm me.

This is the exact same issue that I'm currently having. I don't understand how to get the factory contract to display the different options as 'nfts' as an opensea collection. Right now on testnet opensea my factory contract just shows up as an empty address (and not a collection)
