@badlogic I'm on my 20th or so printed design as a recovering computer scientist, and the few things I've learned so far are that a) one needs to keep the history clean, b) best to add fillets pretty late in the process since fiddling with them retroactively can trash downstream steps, c) it's quite easy to accidentally rotate things not about the origin but some random point near the origin if one isn't careful about the various ways to tidy / lock down one's design, d) snap fits aren't all that hard if one is careful, e) FEM analysis is actually working and pretty straightforward to set up and makes you feel like a real engineer f) their online docs are pretty good
