Bicycle chainguard bashguard

I switched to a internal gearhub and remove of smallest and biggest of the 3 leading gears. This is the protection for the FSA system with removed large star. Not sure, but maybe a it will fit to crankset with all three gears.
It should be suitable for crankset with BCD 104.
I made several models in increments of 10 mm so that you can find your size. The number in the model name is the outer diameter. You can measure it on your gear with chain.
You can make a copy on size on Onshape. https://cad.onshape.com/documents/bf10d43333369e0dc042dac4/w/0e116f503a80b46a00624a9a/e/4c4aa2dbee200faa86079927
In Onshape you can change sizes for BCD and Outer radius in Variables.

Должно подойти для систем с BCD 104.
Я сделал несколько моделей с шагом в 10 мм, чтобы вы могли найти себе по размеру. Цифра в названии м
