This Turtle Flashlight uses one LED light bulb and a penny battery. The shell is hollow and can be stuffed with felt to hold essential oils. Great for cars, dorm rooms, cabins.
Stay tuned for a tutorial on how to design the shell on this turtle using Fusion 360. Follow me on Instructables "flyingpuppy."
I had this printed at Bend's Maker Mill. I don't know the printer or the settings (except that supports were used). The nozzle prints at .4 mm extrusion with .3 mm layers.
Hope that helps.
I don't know why the file shows the turtle on its side. It should be flipped feet down for printing.
