So here are some test I did about the sharp corners Made a fillet curve of 1/4in on all of the corners. I don't like the bottom corner. I think it shortens the fretboard too much Went back to just this bottom one sharp Finally tried a 1/8 fillet curve for the bottom corner I like the softer 1/4 all around, but not decided on the bottom one. Since this is one of the last step, I have some time to think about it. Now going into the shop and leave the virtual stuff for a while.
