@Venom121212 @moon Just checked, the hanger profile is very close to the real thing, but if you want to use it directly for clamps you have to take the profile and offset it outward about 0.2mm or so thats what I did for the 3D printed clamps which fit snug on my hanger. Its the same if you have an axle and hole which are both exactly 10mm for example, you need to make the hole slightly larger than 10mm to get clearance for it to fit. Hope that helps 
EDIT: If I ever mill some clamps with the profile I will see if I can improve it and then update the model
