looking to make my own little tin plate screened boxes..have been making
them, but getting a nice clean tight fold is tricky..has anyone got plans of
a mini folding jig??has to be able to adjust width of fold as will be used
on different sized boxes..typical size 60mm x 50mm x 25mm. with 2 lids.. up
to 150mm x 50 mm x 25mm

The tool used in machine shops for this is called a "sheet metal
brake", and will do all that you are asking for, partial width folds,
exact angle bends, etc.

You might find a small used one out there, but looking at a picture of
one will give you ideas for a home version.

There are plans for building one, which might be best for you, as you
can readily scale everything down.

Acceess to a machine shop for some of the parts would help.
