You are a star. Its not quite what I need however. Imagine the centre area filled in with a box that is52mm BUT is only 10mm deep....THEN another box 51mm square but is back up to 20mm deep.
Essentially creating a 1mm slot that is 52mm square and 10mm deep I then tap in the die rule (basically glorified stanley blades) to form a square with the cutting edges outwards. This will them go into a press to cut out a perfect 2 inch square. in the roofing felt
The 3 D print is really a holder for the cutting blades.
where do you get your die blades from?
i used to get offcuts of 2.5mm (?) to make marking knives, but the bucketfull i had is now used up.
could do with a few more meter lengths (or just 100mm off cuts), but dont know where to source them.
