has anyone ever seen a 3d file for a chock for the one wheel?

So we live on our boat and I need a set of captive chocks (where there is a wedge on both sides) for my GT and my wife’s Pint. To keep them from wanting to slide around the bunk that we store them in. Has anyone seen this or could anyone model this for me? I’m happy to pay for the file if you have to make it.
