This is a battery holder designed for Craftsman drill batteries that can be mounted on pegboards. You can use clips available at Home Depot or Lowe’s at the top and bottom to secure it, or I may create custom printed clips in the future to ensure it stays firmly in place. I’ve also made some updates to improve support. If you run into any issues printing or downloading the file please leave a comment and I’ll get back to you as soon as possible to help resolve any problems or concerns. Thank you
