A great Valentine's Day gift for your wife who loves 3D printing could be a 3D printing pen. This would allow her to create 3D art even if she doesn't have access to a 3D printer.
If she already has a 3D printer, you could gift her a personalized 3D print like a miniature statue of yourselves or a heart-shaped box for storing small items.
Another option could be a gift card to a 3D printing service that could print out a customized pendant or bracelet that she designs.
Finally, you could purchase her a membership to a local makerspace or 3D printing club so that she can connect with other enthusiasts and take her hobby to the next level.
Or you can get her a star map with the date of your first kiss.
