About this 3D model

This is a TPU sock I've created for the great Springy Doorstop by GlennovitS 3D The original doorstop unfortunately slides a lot on my tiled floor. So I've created this TPU sock for it. This is my first design (never used Fusion360 before) - so this is surely not perfect, but it works perfect for me :) Important: this is for the default version (M Size) of the doorstop.
