Always make sure your fingers will be clear of the blade!! NEVER use this in such a way that you could get your hand pulled into the blade. Stay safe!!
The cut I show on my table saw was at 75 degrees and with larger stock would have been VERY dangerous.
I would recommend using this on a band saw because it's less likely to kick.
That being said..
I wanted to make a cut, but was running into an issue where none of my tools could cute an angle less than 45°. (Except my table saw that DOES go to 60, but I needed 75)
This was a simple solution to the problem and it worked fine, but beware, the steeper the angle, the closer your fingers potentially get to that blade.
This wedge was designed to be clamped to the miter gauge or back fence of the miter saw to add 30 degrees.
Math = Whatever angle you need, minus 30 degrees is what you set your saw for.
Example, if you need a 60° cut, then set miter to 30° and clamp this in place to get to the angle needed.
I used a small clamp on that 75° cut to keep my fingers away from that blade and made sure it would clear the blade before proceeding. My fingers never got within 6" of that blade.
The cut on the miter saw was similar. I also made sure the blade was fully stopped BEFORE raising it back up to make sure I didn't get any kickback from a tooth catching the stock.
A band saw would be a MUCH better choice here.
Scaling up - Yes you can scale this up.
Scale X and Y as big as you want, just keep those 2 scaled the same amount to keep the angle correct.
I scaled Z to be exactly 2" tall because it seemed to work best between the different saws. (Or 50.8 mm for you metric folks)
Enjoy, and please be safe.
Print with 4-5 walls and 30% or higher infill so it holds up to clamping.
