1-inch (half) pipe marker template

I needed to mark out half of a 1-inch PVC pipe on material to cut. It would have been easy to saw a small section of pipe for a tracing template, but where's the fun in that? :)

This template is bevelled so any sharpie will fit and give you a nice 1/2 inch semi-circle anywhere you need it. Three depressions provide finger/ thumb support when marking. And it is flat too, so it will fit in any dremel box.
