I completed the process of designing and generating the mold, so you only need to print the mold & handle, create the rubber stamp, and glue it all together.

However, you can create your own stamp design by following the adafruit instructions. It is a fun way to build your skills.

Print the mold and handle.

• I printed the mold vertically with the following settings and the detail was good: 0.4mm Nozzle 0.4 Extrusion Width 0.15mm Layer Height 100% infill No Supports 4mm brim

Create the rubber stamp part.

• I used the Amazing Mold Putty recommended in the article. It was much cheaper on Amazon than at the local craft store. There is enough putty to make dozens of stamps.
• Take a small grape or marble size piece of each type of putty, smoosh and mix them together for a minute, squish it into the mold, scrape it flat, and let it cure for 15-20 minutes.
• Peel it out of the mold and trim the excess.

Glue the rubber stamp to the stamp handle.

• This part required experimentation to find what glue would actually adhere to the silicone-like rubber stamp.
• JB weld epoxy seemed to work best but was more effort.
• Super glue (cyanoacrylate glue) worked well and was easiest to use, but the strength of the bond doesn't seem as strong. I ended up using this in other stamps because it was easy and held up for my use. Make sure to keep pressure on the glued pieces for a minute and maybe lay something on it while it cures.
• Use an exacto or sand paper to score & rough up the back side of the rubber stamp before gluing.

If needed, after the glue has cured and you did a trial stamping, trim off excess areas around the rubber stamp if they leave undesired impressions in the resulting stamped ink (like edges).
