Milwaukee large Packout Custom Impact Socket Insert

This insert is meant to fit the Gen 3 3/8 M12 Impact Driver but would most likely work on later models. The design is not perfect but works well and welcomes improvement from community. The sockets I used for the insert were from amazon along with the extensions, sparkplug socket and 1/4 impact adapters. links will be provided below. The filament used was PETG, I found a color that matched the packout red fairly well, link for that will be provided.
