A combined tool based on the VAR PE-35500 (https://www.vartools.com/en/combined-tool-for-chainring-bolts-var-p828.php).
The tool does have some limitations. If the nut is clocked at a certain angle, the throat of the tool won't be big enough to match with the nut, in which case you'll need to use an actual chainring spanner.
This could be addressed by increasing the throat depth, but doing so weakens the tool.
As a bonus though, if you only ever install your chainring bolts with this tool, the nuts will always be clocked correctly & you'll be able to remove them.
I will likely call this project done unless mine breaks.
