This is a render I created early on in my Blender hobby, I figured I already printed my Robot Buddy which was awesome, so id print one of my older works as well. This is an isometric bedroom from a youtube tutorial.

Each part should not need supports at all. the bed is the only thing im thinking will need supports, depending on the scale you wish to print it in.

Edit: I realize I didn't highlight all the parts of the bed and plant during exporting the STL, so I redid that section and they're labeled v2
