A jig for stamping your bitcoin mnemonic on DIN9021 M8 washers with 24mm outer diameter.
Because of endless warping issues with the original “blockmit” V3 jig design, I made a new, more printer friendly design.
Adjust for your stamps and washer size by scaling and adjusting the hole expansion, if necessary. This model fits 6mm x 6mm stamps with some extra tolerance (mine are more like 6.4 mm x 6.4mm) and has quite tight tolerances for the jig insert. Best printed with low speed for enhanced accuracy.
Use some double-sided adhesive tape on a steel block or anvil to fix the position of the washer and the jig on the block, then begin stamping.
Have fun!
