Repair of the Christmas tree stand

thingiverse

I'm creating a new design for a small pin Christmas tree. It's going to be just 8.7 millimeters in diameter, and 28 millimeters long. The thickness of the pin will be around 2.5 millimeters. I built this model using Fusion 360, and it's my first attempt at creating something like this. I'd appreciate it if you could provide some feedback, but please keep in mind that I'm still learning.
