I made this as a little tool to hold parts of common PVC pipe sizes used for cosplay from Home Depot. While not in my workshop, I needed a tangible and accurate representation of PVC pipes for 3d modeling with. At least I can get some accurate measurements with a caliper while not lugging around the whole entire pipe with me :)
Here's an example of how I applied this for use!
