Terminator With LED's

I got fed up of trying to hollow out the various T800 designs on here, so thought I'd remix this one.

I've replaced the square LED's with 5mm round ones, which meant scaling the model down to 75% to make the eyes about 5.3mm

I've made the hole inside bigger to take a 250mAh LiPo battery, 22ohm resistor and switch and added a tunnel for the LED wires to reach into the hole, and filled in the holes at the back. The circuit uses 7mA.

I had planned to use OpenSCAD but the original model these are all based on is full of errors and OpenSCAD/FreeCAD couldn't render it to an STL - MeshMixer/MeshLab couldn't fix it either. So I used TinkerCAD.
