Hi, I’m new here, been reading a lot, but it’s my first post. While waiting for my trampa board to arrive i want to design and 3d print pulleys. Can anyone tell me the diameter between screws in hypa hubs? And what screws do they use?

Thanks was looking for this info. I tought it was 82mm. Good thing I went looking for the answer :slight_smile:
