A10C knobs for DCS world based cockpits

Re-done A10C knobs for DCS world based cockpits, some are .sldprt models that can be scaled without affecting the splined or D shaft attachment, the others .stl files. I have tried to provide different sizes on some to help compatibility These also differ from the previous ones in that the geometry of the shaft fitting feature has changed to make it easier to get them to suit as there is a shorter spline with a relief behind to allow you to fettle the feature more easily. if you find they are too slack on the splined shaft, I found that putting a little UV cure resin into the spline with a brush, part curing with sunlight or a UV torch and then pushing the spline into position allows a snug fit. You can then cure the resin fully in the spline. If they are too tight, I used a splined multi position switch with a metal splined shaft as a broaching tool. All you do is file the end of the shaft so the spline edges are sharp, and you can use it as a simple cutting tool by pushing it into the splined hole until it cuts the resin sufficiently to give a good fit
