sanwa m12s RS integy wheel adapter

thingiverse

I ordered the Integy wheel upgrade. It stated it would fit airtronics. Apparently they are different. The square on the adapters are a smaller diameter than the one on the radio. I recommend supports to square up the square hole in the adapter. The height inside the square is 4mm. Any sag inside and it won't slide all the way on. Personal experience from my first print. The fitment is perfect on the factory square piece. I recommend running your tiny wheel screws into the five holes first. They too are snug to grip well. After you tap them with the screws, you can add some super glue around the outside of the adapter if you want. Just a piece of mind for myself, but not needed. For the radio nut, it's a m3 size. The stock nut will not fit. I used a m3 nylon standoff, screwed it on and then trimmed it flush with a knife. If it needs changed, I'll just cut the adapter off and print a new one if needed. Not sure how else to secure it on any other way. I included the sketchup file. Enjoy!
