About this model

There are (2) designs for the extruders on the K2 models. This is design (1) for the top of the K2's Extruder to hold the tube in a lot better. Very secure, very strong. I used PETG and heat inserts to mount it to the stock cover. See PICS. Also uses a PC4-M10 Push Fitting. I drilled very small holes into the OG cover, and then put in some heat inserts. (SIZE M3 3x3 inserts) with M3 6 Hex bolts
