There are a few different versions and sizes available. The large, full cutout version is what is pictured in the included images. These are great as a single base in the center of Nutkins. If you want to include 2 (one at either end), you might want to use the small or medium models The partial cutout version provides an end stop that can provide useful if you want to use it in more of a "bookend" configuration. This would probably be more useful in the small or medium configurations. If that's something you have interest in, let me know and I'll toss those together.
