Battery powered tabletop decoration lamp

I've used a dark grey PLA (basicfil) for the colored parts and a transparent PLA for the diffusor. I've set the infill to 100% for the diffusor. 
I might print one with wood filament.
 

I'd love to see a pic of your print! :)
 

Here's the list of components you need beside the printed case: 
- 8 LEDs warm white (3528, I got some pre-wired; saves a lot of hassle https://www.ebay.de/itm/304198347267) 
- 3 batteries (AA) 
- 1 resistor (12 Ohm) 
- 1 battery holder 
- 1 locking switch ((https://www.ebay.de/itm/174133295166 ; "rastend"; "3-9V") 
- 10 Screws (3x16mm; 4 for the battery compartment, 4 for the top, 2 to fix the diffusor to the shaft)
- a few wires

If you want to be on the safe side, you should print the shaft with 100% infill. If you don't mind the hassle and save some material you can use a support blocker in cura and have 100% infill only around the passage from the shaft to the battery compartment.
 

Enjoy!
