Description
I changed my Crank of my bike recently and it didn't have a chain guard to protect my jeans to get smashed and dirty.
The options were to buy one online that means 10-12 GBP or to get a 3D model online and print it with my "already paid" filament.
I went on Google and found one model that looked good and big enough for main Crank but when I tried on my bike, it was too small. What I have done is to measure the right diameter and increase the size to match my 12 cm disk.
Solution
I have shared the model, even if it is not the correct ratio, but people could improve it and print it.

Final result with 4 M4 screws
