I’m building a custom stick using a box that has a viewlix 8-button layout. I want to use sanwa buttons but the top panel is way too thick for OSBFs and the sanwa mounting nuts on OSBNs are also too big and conflict with each other in the viewlix layout. I noticed that seimitsu mounting nuts are interchangeable and work in this situation so I was wondering if there was anywhere I could just purchase spare seimitsu nuts without buying a whole set of seimitsu screw-in pushbuttons.
Yup, you can get them from Akihabara Shop, scroll down to PS-14-G-N and pick G-N from the column in the middle.
Ah, thanks a lot!
