So I know this isn't a machine that you see very often but I like mine quite a bit. Unfortunately the plastic that the center frog shot sits on broke beyond repair on mine. I haven't been able to find a replacement part anywhere so my last ditch is to ask the humans of pinside. Does anyone have a spare one of these or know where I could find one? Also, it occurs to me that this might be a part that could be easily 3D printed. I can't be the only one that has had this thing break in two. Any help is much appreciated!
