This kit is being used for a conversion of an armored transport style tracked vehicle to a wheeled version for 28mm gaming. Each part has been scaled and designed to fit in place on the armored transport model that I used for the conversion without any alterations. If you are using a different model you may have mixed results. The axles have been designed for ease of printing, The tires have been remixed so they now have a flat side making them much easier to print as well, None of the parts in this kit should require supports to be printed, Please leave a comment if you run into any issues while printing.
