Designed in fusion 360.  No supports are required.  Size diameters of the models are in the photos.  To customize own text, download the no text model and add text on your slicer.  The text models are raised so a stop can be added at layer 16 or 17 for single color printers.  Please like, follow, rate, and upload your makes.  Check out my profile for many other models.  Thanks for viewing.
