Bosch 12V flashlight with adjustable head

thingiverse

This is a remix of my Milwaukee M12 system flashlight adjusted to Bosch 12V system battery. It has a head with an adjustable angle, made from MR16 led bulb. **BOM** To assemble 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 featuring M28x1 thread (see photos). - 2 x 8mm length M3 screw. - 3 x 16mm length M3 screw. - 2 pieces of 6.3mm spade male connectors (https://www.aliexpress.com/item/20pcs-lot-6-3mm-Copper-Male-Wire-Splice-Crimp-Terminal-L15-Spade-Connector-Free-Shipping-Russia/32655259302.html). - 1 piece of 21x15mm rocker on/off switch (https://www.aliexpress.com/item/5pcs-KCD1-perforate-21-x-15-mm-6-pin-2-positions-boat-rocker-switch-ON-OFF/32729944207.html). - 10cm of 2-wire cable. - Soldering iron. **Notes** The assembly process is very similar to the Milwaukee version, so check it out to see all assembly steps. I had to bend rocker switch connectors because the switch cavity is a few millimeters shorter than in the Milwaukee version. Please note that the battery direction is opposite to the one used in other Bosch tools. I did it this way so the switch can be placed closer to the battery, and the whole flashlight is shorter. It shouldn't matter in practice. My led bulb uses almost 5 Watts and gets really hot (over 60°C), so printing lamp head with plain PLA may not be enough. I used PETG and it's holding okay. PLA could probably be used after "baking". There seems to be a lot of MR16 led bulbs with M28x1 thread on aliexpress. I checked the MR16 bulb from this page (https://www.aliexpress.com/item/x/32830588347.html) and it fits the thread perfectly. Bear in mind that the power of those bulbs is greatly exaggerated; 9W bulb in reality draws around 3W.
