How can I "bend" a model into a slight curve?

New to 3D modeling, and VERY new to Bambu Studio.

Is there any way to bend a given model to give it a slight curve?

Meaning: I have essentially a straight-edges rectangular model, and instead want to map it to be a small segment of a circle. I don’t want to have to recreate the entire model itself, but would rather just curve the existing model slightly.

Specific details: My son made me an awesome sunglass holder - see https://makerworld.com/en/models/145791 - which works great for straight sunglasses … but mine are wrap-around style, and have a significant curvature to them. So, they don’t fit within the slots in the model which are designed to hold the glasses. I could just extend the depth of the model - making the slots much larger - but that seems to result in a lot of wasted space. A better approach, seems to be to try and approximate the curve of the glasses with the model itself.

Is this modification possible within Bambu Studio?

Don’t think so but I did this quite often with PLA lamp shades.
I just print a positive for the circle I need, like a roll, or for bigger prints make one from cardboard.
The shade or if in doubt lithophane is printed flat.
Once checked and finished off it is place in water of around 80 degrees Celsius for a short while.
A little lip on the roll makes sure all is straight and then I just press it into shape.
A minute or two it is back solid and ready to go.

Mind you that this only really works well for solid prints and not for really thick parts with lots of sparse infill.
With the later you always risk distortion on the outer surface.

Been neck deep in this rabbit hole.

Awesome! This worked perfectly - and I now have both a straight one for my reading glasses, and a curved one for my sunglasses. Thank you so much for the recommendation!

Heck yeah, glad that worked!

I searched for months and tried quite a few programs-

Blender is now one of those programs I really like for certain 3d modeling things.

When you upload on makerworld/thingverse/etc it’ll give you a spot to enter in the original model
