Caliper AAA Battery Adapter

Made a smaller AAA battery holder/adapter with sliding battery cover for the cheaper calipers. Got the idea from https://www.thingiverse.com/thing:1990273. Pictured is V1 of my printed files, the uploaded ones are V2, added ridges to make opening the battery door easier and changed a few minor things on the battery holder. Now, as this is using the stock screws to hold itself onto the caliper you might need to counter sink the holes a little bit, or you could just squeeze a dab of hot glue in the holes before shoving the screw in. Or some 3M double sided tape now that I think of that...

Edit: Uploaded 3rd version, fixed a few things, changed a few things that I missed.

Edit: 4th version uploaded, everything fitting nicely over here, feedback?
