About this 3D model
This is a universal base for the Rigel Astronomy QuickFinder. It is specifically made to fit firmly on a ADM Accessories Mini Dovetail System (MDS) Plate Adapter, but it may easily be used or modified for a variety of other mounts. The key advantage here is that the design contains all the recessed slots needed so the finder "clicks-in" easily and holds securely. Two versions are provided to correspond with the desired orientation of the MDS plate adapter mounting hole. Otherwise, the versions are the same. I designed this in Alibre Design.
