just a reminde in case anyone wants the stls files and bits list. (I mean I'd have to make a list - but I don't mind).

Also here's the world's toughest tennis ball picker-upperer.
it's a 1 metre length of 76mm diameter 3mm thick aluminium pipe !

As well as picking up tennis balls - can also be used for fighting off: dragons, bears, feral wolves, ninjas etc

It was all my aluminium guys had in their 'container of odd bits'
