Bosch 12V flashlight with adjustable head

cults3d

This is a custom modification of my Milwaukee M12 system flashlight tailored to Bosch 12V system batteries. It features a head with an adjustable angle made from an MR16 LED bulb. To assemble it, you will need: - A 3D printed lamp head. - A 3D printed upper section of the body. - A 3D printed lower section of the body. - A 3-5W MR16 LED bulb with a radiator featuring an M28x1 thread (refer to photos). - Two 8mm length M3 screws. - Three 16mm length M3 screws. - Two pieces of 6.3mm spade male connectors. - One piece of 21x15mm rocker on/off switch. - Ten centimeters of 2-wire cable. - A soldering iron. Assembly process is similar to the Milwaukee version, so consult that for all assembly steps. I had to bend the rocker switch connectors as the switch cavity is a few millimeters shorter than in the Milwaukee version. Please note that the battery direction is opposite to what is used in other Bosch tools. This was done to place the switch closer to the battery and make the entire flashlight shorter, which shouldn't affect its performance. My LED bulb uses nearly 5 Watts and reaches extremely high temperatures (over 60°C), so printing the lamp head with plain PLA may not be sufficient. I used PETG and it is holding up well. Using PLA might be possible after "baking". There are numerous MR16 LED bulbs available on Aliexpress featuring an M28x1 thread, but be aware that their power ratings are often exaggerated. For instance, a 9W bulb actually draws around 3 Watts.
