This is a little different, as it's not an illustration, but I figured the group here would appreciate this.
A little back story- I have a book coming out September 1 (less than two months!) that I co-wrote and illustrated with my wife called Pearl and Squirrel Give Thanks. I was curious to see if I could make the main characters into a 3D print. If they came out alright, I was going to send them to some friends and family and to our partners at the publisher. Well, then the quarantine happened, and working on these little guys became my main art project outside of my job. I made five to start but ended up with something like 35 of these painted up... I'm not really a crafty person, so this was a lot of trial and error, but I'm excited about how they came out.
Some more info:
I have a background in games/modeling so I was able to model these in 3D myself but there are online resources where you could potentially hire someone to do the asset creation.
I used a 3D printing service called Shapeways that is pretty reasonable. They print in all kinds of materials- I even got a teeny tiny metal one made so I might use that next time I play monopoly.
The paint was acrylic. I used a brush at first, then used an airbrush on later figures to try to get it smooth as possible. These are tiny, so pictures tend to make them look worse (imperfections are magnified).
I've seen other illustrators have figures or plushes made and that was a big inspiration. Hopefully, this gives others ideas to bring their creations into the real world in new ways.
