Coffin Shelf

I'm still new to 3D modeling and I wanted to try my hand at making a shelf since it seemed simple enough. Everything you see has been hand drawn in Procreate and uploaded to TinkerCad for the build. As you can see by the Procreate screenshot, I am attempting to add drawers to this model. I will be posting the update for that soon as well. I'd love to see how you print and decorate this in the comments! As always, if you have any suggestions about how I can make this design better, I would love to hear your thoughts on that too.
