AA Battery base for glowing moon by Nick_Groot

This is a base with battery holder for the "Glowing moon".
This isn't actually a remix, but there should be a linking to the two objects this thing belongs to, to make sense:
Credits go to Brandon Zhun for his wonderful moon: https://www.thingiverse.com/thing:2531838
and to enif for his very versatile flexing battery holders: https://www.thingiverse.com/thing:456900
I wanted a simple base for the moon which can hold 2 AA cells as power supply for 2 low-current LEDs for the illumination.
So I designed a simple two-piece base which holds the battery case, has a 6mm hole for a standard mini rocker switch, and a snap-fit cover for easy access to the battery compartment.
*IMORTANT** I scaled the moon down to 75% which results in a diameter about 10cm=4" so the battery base has a diameter of 80 mm which might be a bit small for the original size of the "glowing moon" which is 140mm diameter.. You can scale the base up of course but: There is a writing on top, following the circle shape of the cover, which says "The moon 1:34.740.000" which - if i did my maths correct- is the scale factor for the 10cm-version.
If someone wants to print this and needs a different cover lettering, just drop me a line...
The illumination is made with 2 low-current-LEDs in warm white colour. All clear LEDs with the standard housing with the dome shape however produce a sharp, focussed beam. This is not what we want to make the moon glow, but its easy to fix: just use a file or sandpaper and file the dome flat, you can also sand the side parts of the LEDs to make them dull.
Et voila, the LED now gives diffused light.
I soldered two of them in parallel (faceing each other) and simply hung that wire construct inside the moon globe. Sorry i forgot to take pictures and i glued everything together meanwhile :-(
I checked power consumption; the two LEDs only consume about 6mA. With two standard alkaline cells with a typical capacity of 3000mA this moon would glow for about 500hours, which is about 20 days...
Note: of course you have to print the battery holder for 2 AAcells separately: https://www.thingiverse.com/download:763280
(At first i thought it might be a good idea to integrate this into the base bottom, but i think the wiring is more difficult and unconvenient then.)
