Clean wire configuration using 3" heat shrink tubing (careful not to melt your Deluxe Audio Strap wire when shrinking).
I put a 3d printed adapter to the main unit and the DAS prior to heat shrinking. Many of the complaints about the 3d printed adapter was that it doesn't hold. I put a low profile velcro to attach the two pieces then put the adapter on it. This is the perfect solution and has worked wonders. It's like having a hand gripping it together. Originally I put the velcro strap on it but I like clean lines and the velcro was just so bulky.
The battery counterweight was connected with a pop socket and a pop socket holder...I then wrapped the battery with a low profile velcro strap (will end up using an elastic velcro once I locate one). Connect the popsocket adapter with Gorilla glue. It not only acts as a counterweight but you can charge while you play.
