I originally wanted to add a wooden handle but realised that to make a handle strong enough in wood it might have to be quite a large diameter, so I decided to add a metal handle. The handle is made from some 4mm threaded rod with a sleeve of some 6mm aluminium and a couple of nuts. It works well, is very slim so doesn't block access to the TTTTT main box and is strong enough to not flex even when the box is full. That's it for now... I might make a couple more accessories for the box but for now its just gone straight into everyday usage!
