This model is a 3D printable enclosure to make a 100W power bank to charge almost all devices that have a type C charging port (laptops, smartphones, earbuds, cameras, tablets, and other gadgets ...).It fits the IP2368 module which I also created a CAD model for you can find it in my list : https://www.cgtrader.com/3d-print-models/hobby-diy/electronics/ip2368-100w-module-from-aliexpress-to-integrate-into-projects, and a space for 8 18650 cells aranged in 2P4S pack plus a corresponding 4s BMS.And for tinkerers you can add costum leds and stick them in the holes added to the lid part and replace the existing indicators on the Ip2368 module itself because with this design they are far from the surface and are not clearly visible one you colse everything .I'll make a better design to make sure the original leds are close to surface and are visible through some holes and guides.One note: the IP2368 module tself can be purchased on Aliexpress using this link: https://s.click.aliexpress.com/e/_DEe1TMr
