T-800 Head Base - hollow for electronics and battery, 2 parts, with bottom plate

Update: 22 April 2018: Version 2.0.
- Proper snap-fit of the bottom cover. Works so well, it is actually hard to open again. I fear I may need to adjust the position of the rim a smidgen, about 0.5 mm ...
- Separate print of the T-800 logo with pegs at the back to be push-in fit. Made the holes a bit bigger in the base for easier insertion. You can see in one photo with the hole size I had before, the T did not go all the way in, thus the adjustment of the base's hole size for the pegs.
