Enclosure for 5V 2A USB Step-Up charging protection board for Lithium cells
Please support Jamehz by Liking/Boosting their Print on Printables.
This is an enclosure for the 5V 2A USB Step-Up BMS charging protection board for Lithium cells.
It can be attached with any 3.7V lithium battery configuration, namely 18650 cells to turn it into an all-in-one chargeable power bank.
The tray is moulded around the board, while the cover slides over and keeps it in place. There is room for the soldering points inside, as long as the wires are on the USB-A side (where there are no electronic components) There's a hole in the bottom to show the battery status LEDs.
You have the option to have them with USB-A installed, so I've provided both options. Without the port installed it's much more portable, and you can choose to add holes in your slicer for your output wires.
This is the model i've bought - The 5V2A USB-C version without the port installed. It's easier to add a port afterwards than remove it.

Any material will work, no supports needed. Depending on printer tolerances you may need to bump up the case size by a percent if you want it easier to remove.
