Rhombicuboctohedron Solar Post Light
Crazy name right? Wasn't til after I designed it that I looked up what the shape was actually called.. Its a 26 sided shape which a google search led me to its name Rhombicuboctohedron. I designed it around a 4x4 post for outside. I wanted a different colored light other than the white one out there.
The print time on the enclosure will make up most of the time on this project. It's printed in three sections top, middle, and bottom, and 4 housings for the panels. I choose green for the led colors you can choose your own. Just determine the voltage you need to run them and the panel size to charge the batteries during the day. I used this calculator to determine the resistors needed. I connected two 2v 160mA panels in series and connected another pair in parallel to get 4v @ 320mA. I did this for higher current charge.

3d Print Your Parts
This step will take up most of your time building it. I didn't add slots for wires in the middle section so if you have the software be sure to add them for wires to pass through.
Gluing and Making Connections
Solder wires to panels + and - poles using red or black or whatever color you have keeping note of what color is what. Glue the panels with e6000+ to the panel mounts and press them into the open sides. Glue those joints also. I glued the panels first and let them dry before putting into slots. Sanding maybe necessary on all parts. Solder connections according to the schematic attached.
Wrapping It Up
You now have a functioning solar charged led lit lamp post!
