Wall Lamp (Small)

Hi, this is one of my first desings which I've just learned to draw. So be nice when you criticising it. Feel free to ask for improvements.

I desined this small wall lamp for my booknook project. It's suitable for 5mm led. I used Cura for slicer and Ender 3 Pro as Printer. Make sure enable "Print Thin Walls" on Cura. You don't need support just orient objets correctly. You must use glue for put everything together.

My print setings:
Quality: 0.12mm
Shell: Print Thin Walls
Infill: %5, Lines
Material: 200 Bed 60
Speed:30mm/s
Travel: Z Hop When Retracted
Others: Default
