this is a 3D model to be printed dedicated for ceating a power bank using this printed enclosure with the 100W IP2368 module and 8 lithium 18650 cells flat 4 next 4 plus a 4s bms as I'm using the IP2368 module in it's default configuration of 4S battery, you can change that as long as you mind the available space.I should note that the middle piece of this enclosure (named here Box2) is a bit flimzy when printed but it get batter when screwed to the other two. the holes are 2.6mm in diammeter. also you might wanna add a brim to it when printing to avoid any adhesion issues as it doesn't have enough contact area with the 3D printer bed.I will put a link to the video where I show the build of such power bank as soon as I edit and upload it.
