In common with my ancient Ryobi 18V drill 4 of the cells are in the D
section leg that plugs in the handle and the othe two at right angles at
the bottom. Having something sticking out a bit further is no great
problem so I thought of trying 2 strings of 3 2500mA AA Nimh but cannot
find a battery holder.

Don't think a battery holder that allows the cells to be changed will work
well. For best results the cells need to have welded connections.
Re-chargeables can supply a lot more current than alkaline.

Yes but for my occasional use the heat from the resistance between
cells may not be an issue, it just means I can carry on using the tool
rather than dispose of it.

Think you'll find the performance so poor you'll no longer want to.

That's why I 3D printed some HD D cell holders because the std ones
would just melt as soon as you tried to put any real current though
them. And if you are cycling 7Ah cells you generally do have to do
just that.

I did try the std offerings but the contacts just melted through the
clip. ;-(

Yet most 3D printers specifically use plastics and materials than melt
at low temperatures.

Mine can do ABS so can cope with boiling water temperatures but not
all/many do. Most people use PLA.
