We just recently picked up a second hand Ikea Duktig Kitchen but it only came with 2 hangers for the bar. Without being able to purchase more from Ikea, I started up my CAD program and a few short hours later, make a near replica in PLA. It's only slightly larger on the hook end, to ensure utensils and pans can hang easily.

Photos show the original vs my printed one.
