In order to efficiently mint and distribute NFT wearables for all our buyers, we need to setup a merkle claim contract so users can pay the gas cost when they claim.
Requirements:
Merkle distributor contract should be able to receive 1155 NFTs
Users should be able to claim all the NFTs available to them in one transaction (can use BatchTransfer function from 1155)
Should allow for ongoing distributions of assets with new merkle roots

Requirements:
Sandbox has developed a lot of this functionality in their contracts so we can likely use that as reference: https://github.com/thesandboxgame/sandbox-smart-contracts/tree/master/src/solc_0.8/claims
They even have a merkle distributor contract that supports ERC20/1155/721 all in one.
Here's the JSON and code used to generate the merkle trees: https://github.com/thesandboxgame/sandbox-smart-contracts/tree/master/data/giveaways/multi_giveaway_1
Known Origin also has something similar, but only for 721s for now: https://github.com/knownorigin/merkle-royalties-distributor/blob/master/contracts/MerkleVault.sol
