Accessory Dovetail for telescope finders - modified to fit a 102mm Maksutov or other radiused optical tube

This hardware-free tapered dovetail is about the best thing I've found for finders and accessories (PiFinder) on my telescopes and Analog Sky Heart 3D printable binoculars!  I love this thing so much that I've started making remixes to fit the original flat-based model from @steriva on Makerworld to fit all of my most commonly-used instruments.  The dovetail slips into the base and wedges in with a double-taper - width and height and stops with great grip!  You have to push your accessory back out by pressing on the narrow end of the dovetail, but then it comes right out!  No accidents or failures at all in many weeks of using this design!  Here is a version that fits great on one of my favorite grab-n-go scopes - a 102mm Mak!  This is specific to an Orion Apex scope, but as I recall, the Meade was the same design.  Make this thing in under an hour and bolt it to your telescope and start really enjoying not using dubious thumbscrews to keep your precious finders and accessories!  I think you'll love it!  Big props to https://makerworld.com/en/@steriva for the awesome design!!
