Hi there! I’m new to 3d printing and modelling and I have this file for a part on my RC car. I need some help stretching it to the dimension shown in the design picture. As that all the screws still need to fit I would like it if the stretch only happened between the red dotted lines. Is this possible? I’ve attached the original file too.

Thank youuu!
