Pendix ePower 300 holder for IKEA Elvarli shelving

Ok, super specific use case, but who knows? It'll maybe be useful for someone, or at least for inspiration for someone.

Made a holder for my Pendix ePower 300 battery so I have a fixed spot for where the battery would charge. It slides onto the shelf structure of the Ikea Elvarli system.
