A basic dovetail stamp handle with interchangeable and fully customizable plates.
I have included the step file so you can alter and create your own designs for the stamp plate as you see fit.
Printed out of 0.2 layer height and PETG for the flexibility and use supports for the bridging, they are fairly easy to remove with 4 Z interface layers and 0.2 Z distance.
