I had a buddy make this one for me and I love it, he made a few dozen for Miata's (which he had ). He sold them on-line somehow but I can't imagine it making you money. The buddy just enjoyed woodworking challenges mixed with engineering so this dovetailed for awhile. Selling made it non-fun eventually. This one has a female threaded insert inside to receive the male thread as I remember, it stays on fine but you can break it free if you twist hard. Think you will work hard for un-appreciative strangers making them as a business. For friends, much more satisfying. The little imperfection in the grain makes it unique in the bare hand, can't remember the wood type.
