I have developted this accessory pack for Big City Robot which will take advantage of all the extra 5mm ports I have added to the 2.0 version. As I think of more city like features down the road I will design them and add them to the set. For now there is a Comms Relay, Flight control tower, Spire, Turret, Spot light, Missle pods, and a small shuttle. Some of these items allow for light up feature which would require LEDs as indicated in the download package. All items have a rotatable base and some items have more articulation then others. The large storage container can hold 1 Fight control tower, one Spire, and a larger variety of the smaller items in multiple. The Storage building can also serve as a backdrop for Big City Robot when in City mode as it is fairly large. Check out my Youtube video on the set to get an idea of how the accessories look and function. I may add more accessorie items that are city or robot related in the future and will update here as I do.
Also I have included a step file version of the 5mm peg as tolerances can make it too loose or to tight so edit the peg portion of that file as you see fit but leave the portion that plugs into the base for each item as it is.
