Blockmit Cold Wallet Washer Stamping Jig - enlarged

Remix of the Blockmit Jig for stamping a cold wallet backup on washers.

The wheel diameter hole has been increased to 6.7mm to accommodate slightly larger 3mm letter punches.

This remix is for the wheel only. You should use the original jig body from @muchtall.
