This is a model for a replacement finger nut for BMW Airhead Motorcycles. I made this to replace some missing ones on my bike. the hole is 5.5mm. you may need to drill out if you have trouble running an M6 tap though it. I was able to get an M6 tap to go through.
Print at 100% infill, Drill/tap hole for M6 threads.
