About this 3D model

Made this as my second ever Fusion 360 model and wanted to get a little more advanced with it. Printed with auto trees but they will definitely need tweaking as seen in my printer photo that tree in the window can be difficult to remove. Additionally, I thought I provided enough tolerance when creating the opening, but it is a little tight yet works great still so keep that in mind. This was all done with PLA. Overall, I have an addiction to printing and Nicotine so might as well combine the two and make my cans make sense right?
