Does anyone know what this part is called and where i can get another one???
EDIT: the part is the broken thing the finger is pointing at.
That’s a #10-32 fitting. You can confirm by testing it with a 10-32 bolt.
I don’t remember what the larger side is, but you can measure it.
You can replace it with an alternate fitting such as this 10-32 to 1/4inch connector
or some variation such as this elbow
I looked up your original part and it’s Bimba part number is D-855-A
