18650 Battery Case (x4)

Link to Fusion360 File (because makerworld hates me for some godd*mn reason and won't let me upload it)

TL;DR: 

This is a very simple 4x18650 Battery Holder. It is made to have nice clearance on all axis' to ensure that no matter what wrap you have (stock or aftermarket) it should fit nicely inside without being too snug. Download it, print it, forget it. Its one of those prints that work so well you don't even think about it. 

The lid is held on via tension. It is not too difficult to pull off, but still snug enough that you can throw it in a bag without worrying about your batteries falling out. You can hold this case upside down fully loaded with 4 batteries and none will fall out. 

I recommend using PLA instead of PETG as PETG is a little more “slippy”.

It has been created to “break-in”, so it'll feel a bit tight at first. This is normal and is intentional. Simply take any graphite pencil and draw a few lines on the connection points on both the male and female ends to lubricate the connections. After putting it on and taking it off about 8-12 times it will be in good working condition. You'll likely be annoyed that its too tight at first, but I assure you that it will indeed break in quickly and having it too loose is an absolute pain in the butt. 

I printed this a few weeks ago and have went on a few trips to test it out and I am pleased with the design. Its simple, strong, effective, and doesn't use much filament with a quick print time. Will fit all brands of 18650's with all brands of wraps. They won't get stuck in there, but also won't rattle around. 

This model is nothing fancy; But it doesn't NEED to be. It holds batteries… sometimes “good enough” is exactly what you need. 

I made this out of spite because I downloaded a model that was similar to this but it absolutely sucked. It sucked so much I went out of my way to make a better one that actually worked so people don't have to waste their time and effort on some nonsense design that wasn't even tested. 

I'm not mad, YOU'RE mad. 

I added texture for grip and aesthetic. I tried a version without texture and it was so boring looking. If you want it anyways its in the fusion360 file.. somewhere.
