Pifinder Bottom / Mount to Hadley

This is a merge of two parts, the part “Bottom” of BBLab's PiFinder, and the part “Test_Print” from Maff's Hadley Telescope.  Print time on this part is just a bit longer than BBLab's Bottom.  It will eliminate the need to print the dovetail mounting hardware and figure out how to get a dovetail on your Hadley, AND reduce the need for four heat stake inserts and related cap screws.
BBLabs noted that folks might need a left or right hand version.  If this is oriented wrong for your configuration you can fix it in your slicer by doing a Mirror around the X Axis.
