In my opinion the 1.5 notch depth at the 30 degree angle is not something that can be fudged to look about right and then say you solved it. Matching all given dimensions is as much of the puzzle as matching the geometry. (Although I think we had one recent puzzle that had dimensions impossible to entirely match.)
As for solving it myself, I’m out with COVID and have no computer access for a few days. I’ll be sitting this one out.
