Patches of following factions:
Brotherhood of Steel
Railroad
Followers of Apocalypse
Minuteman
Enclave
Vault-Tec
Beware, if you print the Minuteman patch Preston may appear near your printer...
Printed from TPU
I was not able to print the BoS patch due to my printer imprecision (nozzle 0.4). With more precise printer it should work just fine.
