To start off my apologies if this question seems somewhat unclear. For context I am attaching the images of the model and the modified version in TinkerCAD. My issue is that I cannot fill in the gap on in the left arm of the gripper without these deformations happening.
What I would like to do is to fill in the gap and then make a hole that fits the servo motor head. At the moment the printed model loosely fits on top of the servo motor and when screwed in place does not have the range of motion I need.
I would be extremely grateful for any suggestions on how to fill in the gap without the problem occurring in TinkerCAD. I know I may not have tried the most sophisticated solution by just filling in the gap with another shape but I could not modify the model in any other way.
