Working Lamp from leftovers

So for some reason I had two batteries and two lamps laying around, and I decided to make a working lamp out of it.

No charging circuit yet - comes in version 2.0 :D

The battery:

The lamp:

The switch:

The fuse:

Bolts:

It's all M5, on the top in the holes insert a nut, don't tie it till it breaks :)

Some more notes:
I printed it with 15% infill, the housing is ~1mm wider in both directions than the accu, I plan to put there something so it does not rattle inside.
Some basic soldering is needed, from the battery + and -,
- goes for the black wire on the lamp, + goes to the fuse, fuse goes to the switch other terminal of the switch goes to the red of the lamp - c'mon you know this.

For fues I recommend a 3A type - as long as it is smaller than the short circuit cu
