I made a wood heart-shaped holder (frame?) to hold a matching pair of ammonite fossils my wife gave me when I had to move away for several months for work.
This is how I took an inexpensive IKEA JANSJÖ lamp and replaced the heavy base with a magnet so I could use it as a work light on my shop tools. This video also contains a very basic Autodesk Fusion 360 tutorial where I show how I modeled an adapter that I printed on my 3D printer.
