2xAA carrier

I have a small single cell AA flashlight as part of my every day carry. I needed a way to carry spare batteries for it. There are numerous options on Thingiverse and I've used a few but wanted something that I can carry on a belt loop. There are a few and some are really good like https://www.thingiverse.com/thing:5356066. The issue I have is that the loop used to allow the carabiner to do it's job is particularly fragile due to the layering inherent in 3D printing. I designed this version to address this issue. I used 2mm UHMWPE cord which is extreme overkill (considering it's break strength is 620 lbs). I used 5 walls which effectively makes infill almost 100% so it's pretty strong. Any cordage around 2mm can be used. I printed the holder using Overture PLA Pro which is pretty strong. I used knots in the end of the cordage to lock it in the recess holes. The knots were a bear to pull into the recess holes but if you work the knots a bit they will pull into the holes. Glu
