I designed this mount so that I could use my Telrad with the OpenAstroTracker (https://www.thingiverse.com/thing:4167783). It uses the mounts for the guidescope (https://www.thingiverse.com/thing:4181640) and does not need any modifications. For those who do not know, a Telrad is basically a reflex sight for telescopes.

HARDWARE: 2x m3 x 30 screws for securing the Telrad to the base. 6x m3 x 20 screws for securing the feet to the base. (2 In the center holes is fine.)
