I have many odd objects in my house, but I think the oddest is the 3D printed model of my teeth (with my braces on them). Long story short, these had to be made when I got my retainers, but I was lucky enough to be able to take them and my braces home. (Don't worry, I thoroughly disinfected and cleaned the braces before gluing them on.) I genuinely forgot I had this, so finding them kind of startled me at first.
Here's the second pumpkin I carved (I did find the sketch, so I posted that in there too). Both carvings were really fun and very time consuming. I'm usually not good with 3D models or sculptures, but carving pumpkins seems to work out.
