This was a modified version, but printed and works well.

Strength Issue:I printed 2 and they lasted about 24hrs and then sheared off at the wall. I had a drill on one and an impact driver on the other.
I ended up splitting the model and mirroring it to create a plug and used that on the battery holder - this gave it enough strength.
If printing this model, it is only for very light tools.
I used this on a drill and an impact driver and it worked great, unfortunately, it lasted 24hrs and it sheared off and they crashed to the ground. May look at a way to strengthen it, but at this stage I would say to only use it for very light tools.
It was pretty weak unfortunately. I was able to put a small flashlight on it, but would not trust a drill or the like on it. I love the concept, I think if there was another honeycomb connector directly below it would provide that extra weight holding capacity needed.
