I recently had the level knob on my grail module fall off while jamming and was wondering if anyone knows what size/type of screw it is on the knob? I'm assuming I have to tighten it back onto the stud part sticking out but by looking at it I'm unsure of the size/type. It appears similar to a hex style but more circular. Let me know if you have any input. Thanks!
