A threaded adapter to convert older metal dumbbell weights for use as counter weights with a Skywatcher AZ-GTi in EQ Mode.

A length of M12 threaded rod is used to be able to thread into the AZGTi along with two of these. Once printed one goes above and one below to interlock the weight.

Depending on printer and material the threads are a tight fit and final cutting will be done on the first threading. I would print one out and test initially

I printed the prototype of these in ABS using .20 layer hight, 4 walls and 20% Gyroid infill.
