Parkside 12V flashlight with adjustable head

This is a remix of my Milwaukee M12 system flashlight adjusted to Parkside DCBK-70-12 battery used in Parkside PBSA12B1/PABSW10.8 screwdriver. It has a head with an adjustable angle, made from MR16 led bulb.

BOM

To assembly it, you will need:
- 3d printed lamp head.
- 3d printed upper piece of the body.
- 3d printed lower piece of the body.
- 3-5W MR16 led bulb with a radiator with M28x1 thread (see photos)
- 2x 8mm length M3 screw
- 3x 16mm length M3 screw
- 2 pieces of spring type metal sheet for connectors (see photos), The wider part is 6mm, the narrower part is 4mm wide.
- 1 piece of 21x15mm rocker on/off switch
- 10cm of 2-wire cable
- soldering iron

Notes

Assembly process is very similar to Milwakuee version so check it to see all assembly steps. There is a small difference - due to difference in connectors shape I pushed connectors from the inside of the battery socket and I soldered wires afterwards.

My led bulb uses almost 5 Watts and gets really hot (over 60°C) so printing lamp head with plain PLA may be not enough. I used PETG and it is holding ok. PLA could be probably used after "baking".

There seems to be a lot of MR16 led bulbs with M28x1 thread on aliexpress. I checked MR16 bulb from this page and it fits the thread perfectly. Bear in mind that power of those bulb is greatly exaggerated, 9W bulb in reality draws around 3W.
