If the lack of chain guards on aftermarket chainrings is one of the reasons you are sticking with the limited choice of Brompton chainrings and cranks, I have a solution for you!

I just released my easily modifiable 3d model for a chainguard that fits most chainrings. You just have to measure, input the values, and it will generate the model for you to print.

The file is here: https://makerworld.com/en/models/2637304-bicycle-chainring-guard#profileId-2913261
