IKEA's TUPPLUR rollers are perfect backgrounds for object photography. The only problem is when you don't have enough space to hang them up. I have a desk with two IKEA SIGNUM cable organizers underneath the tabletop so I designed some hooks to hold the TUPPLUR (or any other) rollers for me. That's how I converted the bottom of my desk to an object photography station. I made 3 different hooks so choose your favorite, print and enjoy your desk's extra functionality! The "TUPPLUR spool lock.stl" model just helps to hold the TUPPLUR roller together.
