Universal Cordless Drill Holder

This is a drill holder I designed for use in my and my grandpa's garage. I've tested it with DeWalt and Bosch drills, but it *should* be universal. I tried to get the best balance of looks/strenght/plastic usage, but I'm currently designing a honeycomb hole model that should use even less plastic.

Please tell me if there are any issues with the model, I'm only a beginner at modelling so I'm eager to have feedback
