Bike rear light

This is a very visible rear light for my bike. Red lighting area is 79x50mm.
I used black and transparent PETG for part printing.

Electronic parts are :
- 94x50mm 15W COB LED Light Panel Lamp 12V.
- LiFePO4 cell 26700
- Battery poles spring contact (one negative and one positive)
- MT3608 step-up module
- KCD11 Rocker switch
- A power jack
- 4x M2.5x15 countersunk screw (frame)
- 4x M3x8 screw (mount)

The COB led isn't used at full power. Output voltage of the step-up module is adjusted to obtain the right brightness without burn neither eyes nor Mt3608.

I plan to update (one day...) the step-up with a LiFePO4 charge driver, cell protection and step-up on the same board, with USB-C connector in place of the jack.
