I’ve designed a multi-parts model for 3D printing that I need to add around 0.05 to 0.1mm tolerance to the connection cutout. I’m currently doing that manually on the model itself but it’s not ideal as I then have a hard time align the parts properly to make a render for the assembled product.

Is there a better way that I can add tolerance on the models so I can use the exact dimensions on sketches for modelling and export the step files with tolerances for printing later?

Thanks
