I originally did these for my own NBA Jam board to help minimise cables on this stack. A few other people have been interested so I thought I would show off my knob
I had a few people enquire about these. Which has prompted a few things. Yes I have a few for sale (I think there are 4 left but I could do more if there was interest). They are $35 USD shipped to the US or $35 AUD shipped locally. And as people were interested I thought I better do a knob for your knob so I printed a few colors.
Thanks for letting me know they turned up. Let me know how they go. I have only tested personally on NBA Jam but have a list of boards others have tested on.
