My first tutorial with Fusion 360 let me create a functional model of a generic stamp holder that allows the user to customize any stamp he may need. I did not see any like this customizable.

The custom creation of the stamp is pretty easy using Tinkercad or any 3d software and just add your SVG image or custom text to it. 

I can help anyone that needs to update the design with their custom stamp or in the future add a small tutorial video how to easy add a custom stamp using an browser based online video.

Note: Printing in progress to test fit and other elements. I will be back with more details.

Let me know in the comments if any other elements may be needed.
