The Skywatcher Stargate is a truss design that has little space to add anything. Is possible to add a Telrad, but in a very uncomfortable position. That is the reason of this design, it allows for a telrad on one of the trusses.

Printing:

Possibly will print without support, but I did not try.

Usage:

Attach it to the truss no. 6 (left one) using plastic cable ties, long ones.
