This is a simple 18650 battery pack enclosure. It is made for a 3S2P configuration or vise-versa (holds 6 batteries). Be mindfull of safety when using Li-Ion batteries. I will print this in PLA but would definetly recommend using PETG if you plan on using it on the field. This is my first thing so feel free to comment or ask me stuff you would like to know about it. The cutouts are designed to hold an XT60 male connector (might require a bit of filing to get if perfect) and a 15mm toggle switch. Enjoy ;)
EDIT: The parts didnt match due to a design flaw. I updated it with a corect lid and a square toggle switch design since I ran out of round ones...:O

-I added the .step file if anyone wants to modify it for their own use.
Printing in PETG or ABS will result in a much stiffer end product. If you will use this everyday than be sure to print with a better material or at least 30% infill. I use triangular infill.
Use a simple heat gun or gas soldering iron to clean off any possibile strings. I recommend printing this in ABS if you can. Otherwise I love using PETG over PLA but they both work fine in ths case.
I used Fusion360 (Students license) and a pair of decent calipers to desing this. I already accounted for the clearences so there is enough room even for a BMS (a must) and a fuse as a preventitive measure if the BMS fails. Use thick enough wires-there is more than enough space for them. I recommend a 5A fuse but that mostly depends on your BMS and battery specs. The body and lid snap together but dont be afraid to add a dab of super glue to help retain the parts together.
