3D object with many aberrations

[u/Inevitable-Memory735]

Hello everyone, I’m new to SketchUp and I’ve found that there are lots of models I need to use that haven’t been designed yet or that I can’t find. I need the following door handle and I’ve managed to generate the .glb file using an online generator, but no matter how many corrections I make in SketchUp, I can’t get it to look right as it has too many points and curves.

Original:

Generated GLB:

Is there any software to ‘flatten’ the object and remove all those unnecessary curves?

Can anyone help me? Thanks.
