Piggyback adapter for Synta/Vixen telescope finder bracket

The prototype will be printed next week, but as it isn't a complicated or particularly failure-prone component I went ahead and uploaded.

The only other part necessary for this adapter is a 1/4-20 screw. It's a piggyback adapter useful for attaching guide scopes, cameras, Skyscouts or other accessories to a telescope equipped with the ubiquitous Synta style dovetail shoe. Please note, this will NOT work with refractors in which the finder bracket is integrated into the focuser assembly. This is because the adapter is designed to be loaded from the opposite direction into the bracket with a large stop designed to prevent the accessory from sliding out the back and onto the ground if the screw is slightly loose, something which has always bothered me about the design of Synta finder shoe accessories.
