Help! I have a Qidi Tech 3d printer and the push release to remove the plastic filament rod from the feeder head broke. I patiently tried pushing it to release for about an hour but no luck. Then it finaly broke so now i need to get new parts. Not happy camper right now with Qudi Tech but hoping someone here can stir me in the right direction to getting this fixed. Here are two pics of the damage and thx for any help!
