To fit the Orion (Bintel) dovetail base to my Canon 400mm F2.8L lens, I came up with this little gadget.

Adapter is made of two identical parts, glued together with acetone (so 3D printing is possible without supports).
Also, couple of weeks ago I made dovetail->red dot finder adapter...

If someone is interested I will post stl files here.
