Mushroom Lamp 175 percent with 12v LED

This is essentially a remix (see above) from Thingiverse.  Kudos to the designer, I am not worthy to call myself a designer.  I modified it to use a 23A battery (12v) and a 12v automotive LED cobb light.  It's very bright, and the battery should last a long time.  Replacement batteries are cheap and easy to find.  I had to break the model into pieces to print it on my printers.  Plus, many people had the original small version fail to print due to lack of support issues.  This way, you can print only the steepest angles with support, and the rest will print nicely without support.  The mushroom “spots” need support, but with a “z” gap of 0.24mm, the supports easily pop right off.  I used infill of only 5% on the parts, but 20% on the supports.

The arch that holds the bulb holder was just a piece of flat, printed PLA that was lying on my table from another project.  You will have to make that stl file.
