Add QR code to images of your 3d model?

Hi Makerworld.

Is it allowed to add an QR code to the images or to the description section of your model?

I have a simple keychain with boost me that is being sold aswel to help fund the rechearche of Parkinson.

The Parkinson foundation that we is being used for it has provided a QR code to donate directly.

I would like to add it to the model description or in one of the photo’s for ppl who want to help.

Is it allowed?
