In this Instructable I will show you how to create your own inkpad stamp using 3D printed handles as the base.

Step 1: 3D Print Your Stamp Handle

In order to do do custom sized stamps 3D print the stamps. Using this model http://www.thingiverse.com/thing:47966 and OpenSCAD a base for the stamp with a handle can be crated to any size you would like. If you are not comfortable writing code in OpenSCAD you can also use this model and scale it to your needs. http://www.thingiverse.com/thing:5676.

Step 2: Prepare Your Sugru

This part is really quite easy. Roll the Sugru in your hands until it is about the shape of the stamp base. Push it onto the stamp until it is evenly distributed.

It is OK if excess goes to the edges. It can be trimmed later with an exacto knife. I recommend that you push the stamp with the fresh Sugru onto a flat surface in order to make the bottom nice and evenly flat.

Step 3: Create Stamp

You can create the stamp by removing areas using a pencil or pen and drawing on the Sugru. This works pretty good but be sure to wait until it has cured before using the stamp.

I found that it is better to use a new piece of Sugru, roll it out to the approximate shape of the stamp and with an exacto knife cut out the shape or image you would like to see stamped.

You can also add items to the stamp by pressing into the Sugru and when it cures the item should be secure. Be sure your item has a lot of texture and will be able to handle in the ink providing an effect you find acceptable.

Step 4: Start Stamping

Using an ink pad found at pretty much any craft store, you can start stamping away.

<p>What if you also use the 3D printer to design the actual stamps as a mold to form the surgu?</p>
<p>I did go through many hours and iterations of 3D printing molds for use with Sugru. I had a hard time with resolution on a small scale and that is what led me here. The first thing I learned is that you would loose too much definition as the Sugru covered the 3D printed area. In many cases if the shape to be stamped was small it would start to be unrecognizable. I was trying to keep my stamps small enough to be cost effective with the Sugru (half a packet per stamp). </p><p>I found that using a sharp knife or a simple shaped mold to take an impression worked best. For example, here is the 3D printed part I used to take an impression and make the S stamp (part from this Thing <a rel="nofollow">http://www.thingiverse.com/thing:175416) </a> </p>
<p>These turned out great. Seems like a pretty slick way to make some custom stamps. Nice!</p>
