As well as their plastic sets, Wargames Atlantic have a growing digital catalogue of 3d print files, some of which can be purchased as a physical product from Only Games (https://only-games.co/collections/wargames-atlantic).
One of these sets is for civilian Cannon Fodder providing three new body pieces (seen below) and multiple tool carrying arms.
I plan on creating a scenic piece using Cannon Fodder to represent an Imperial Guard motor pool. Basic upkeep on armoured vehicles being conducted by Guardsmen with an Enginseer looking over.
I may even look at converting a Munitorum Container to be the tool shed.
