This is the TFXTOL 214-3341, which is a "copy" of the 3M ZIF socket. There is a 3D model available for the original 3M part (214-3339-00-0602), but it's not quite the same dimeio as this Chinese part, so this model is done from measurements of a real 214-3341. 2 assemblies with the lever up and down.Used for programming ATTINY 84/85
