...The question should be with your model why didn't you make and individual one that will clip to it's neighbor for solo or multi cell printing Keep on Fusioning .....
Yeah, I thought aboot doing that... then I realized that
A) Those kinds of projects always look like ASS because of keystone/dovetail joints,
B) they always use a lot more material,
3) they're never as rigid as a single printed piece, and
D) I don't have to do that much work just for the sake of other lazy dumbasses who can't be arsed to do a couple minutes' layout work in the slicer for their custom-sized 18650 cell holder.
Here's the 1S version; as you can see, it looks nice & tidy as-is just hacked off the whole model. I made it slightly oversized; 19mm wide slot and the contacts are a bit loose (on a plain cell with no button they compress the contacts aboot 2mm each) to accommodate both button-end cells and
xP cell groups like this where the tab is still attached and folded over.
3P cells like this are probably the single most common layout I've found in busted laptop packs; it is easiest to work with multiples of 3 either as a 3P cell or if you need 1P packs, to build from these 3P cells as they are likeliest to still be pretty well-matched to each other. All you have to do is find 2 3P cells with similar IR and tested capacity to make a half-decent 6S1P pack, for example.
Right now I'm printing a 2S version made of just this part overlapping itself in Cura; preview looks perfectly happy with this, so we'll see what the ol' DIGGRO turns out.
