The file 'Box Case For HW-681 Power Converter Dual USB Charger Board 3a (6-26v To 5v DC-DC) 3D Printer Model' is (3mf,stl) file type, size is 202.3KB.
This box allows you to protect the circuit in the HW-681 charging module.
The charging module allows (on my board, see details on others) an input range of 6-26v DC and has an output of 5v DC up to 3a between the two ports.
The design that I attached is pressure-fitted so it can be a bit tricky to disassemble it again without damaging any support embedded in the board. I recommend soldering the cable first and tying a knot before placing it.
In the box we have some holes for the cable output that allows you to tie a knot and avoid damage to the board if you pull the cable a little.
