About this 3D model

Whilst doing work experience at MyMiniFactory, they had a camera lens cap which they 3D printed and the mechanism didn't come out correctly, so I was asked to redesign it so it was support free. The purple cap is not of my design, nor have i included it, please download it from the original authors page, which I have listed down below. I found the original model on MyMiniFactory; https://www.myminifactory.com/object/3d-print-58mm-lens-cap-1693 Please go check it out, its a really good design!
