This ink stamp has a modular design to allow you to switch the stamp end. The stamp plate uses a dovetail joint to hold it in place. This way, you only need to print one stamp handle. this design also allows you to print with the business end of the stamp plate facing up.Print out the Stl and assemble with one m4 flat head bolt shorter than 40mm. of course, you probably want to change the wording on the stamp itself, so go and edit the skp file and export your own stls.Oh, and as qharley noted, you'll need to mirror image the text (unless your making a "redrum" stamp).
