About this 3D model

I made this wheel for a 1/4 scale SiSt FW190 that a friend of mine is building. It can be scaled down for other sizes, off course. At this size the tire is designed to be a plug for making a silicone mould for casting rubber tires. Smaller versions can be printed from TPE and them carefully bonded together with a soldering iron along the seam. Twelve M3x35 mm screws are needed to assemble each wheel. The center hole is 10 mm, and needs a 10x8 mm brass tube to work as a bearing surface. If the wheel is scaled down to for example 1/5 scale, the bolts need to be M2.5x28 mm screws, and the center hole will be 8 mm. For personal use only, not for resale or redistribution.
