Battery Holder for a popular brand of power tool batteries in Australia

I have a plethora of power tools in the farm shed, workshop and office.  With these, collected over many years of renovating, comes a number of battery capacities at 18V, ranging from 2 - 6 Ah, as well as numerous charges.

Why not use these handy power sources for other projects?  I'm working on an outdoor mobile platform design and needed a reliable power source, so I made this adapter.

I have no commercial association with the manufacturer or supplier of the batteries, except buying them. I suspect that any warranty will be considered void if the batteries are used with a non-genuine appliance.  They are very popular in Australia, I'm not sure if that is the case elsewhere.

There are two printed parts, the holder and a protective clip.  One part is required that might be hard to obtain is metal battery connector.  I took mine from a broken power tool I pulled apart. There's a part number which may help.

Print holder, it has lots of supports, but you don't have to be to accurate with the cleanup as they are all hidden.  Be careful around the side clips, which need an accurate profile (second pic, at bottom).

Next insert the metal connector.  And then press the (printed) clip on - may need a small tap as it is designed to fit very tightly.

Look from bottom, should look like this.  

The adapter is designed to be mounted upside down in my application, hence the mounting holes.  FreeCAD design file included.

And that's it - Power Up and be always be safe with Li-Po.

See it in action here..  doing something more than running power tools.
