Just printed this.. Excellent design.. But I think there might be a TINY problem with one of the models. I can't tell whether its the 30 or 35 degree one.. But when you line them up by the hole and look at the tips, they form a nice slope as they get progressivly longer.. But when they get to 35 its about a mm too long.. And 30 perhaps a little short. Here is a picture https://ibb.co/B2HVbbr And also in the same vain, the 10 and 15mms are a lot shorter than the others, but perhaps thats because they are so thin. Its not a major problem, just an observation
