I think my brother did this when we first got the printer, but simply put, I believe the mistake is mine. I eyeballed a few numbers and didn't account for some specific things.

I missed a few rounded corners and in one place I clearly measured from the wrong spot, I'm more than a couple millimeters out.

It's pretty close, and honestly, really good for a first try, if I do say so myself.

I kinda knew it wasn't going to work right before I hit print, but I couldn't, or rather, wouldn't, guess, not check everything just to find out what I bodged.

I'll get on it tomorrow, hopefully. Even when I get out to fit, I'm going to need to make adjustments to make it work in my application. For now, I just want one that fits over the battery.
