I need a 3MF 3D file edited. The task requires adding or removing details from the model. I have this 3d model for this grip that goes over a Tpu shell for the ayn thor. This grip has textured handles and a stylus holder In the middle. I just need the texted handles on the back to not be textured and just smooth and I need the stylus holder removed so it's just a plan flat spot like it wasn't there.
