This is a customizable cat scratching device. I've included the solidworks files so the custom text can be added to each piece if desired.
One of each component (leg, leg_mirror, post, post_mirror) needs to be printed. I printed mine with the wood-like PLA from Hatchbox. The bars across the span of the scratcher are made from ½" diameter dowel; each one is 8" long. The dowels are secured with simple wood screws, but there should be room for socket head cap screws if desired. I purchased the sisal twine from amazon and wrapped it around an old tennis ball. It is secured to the ball with glue.
