I’ve been using an IKEA KALLAX for my manga collection, and I wanted a riser to display a second row properly. Most of the models I found used way too much material while not actually being that strong. This version is: Much more material-efficient Surprisingly sturdy (tested around ~20 kg load) Includes a 15 mm rear lip so it doesn’t fall behind if you have plinths. You can fit 2 risers side by side in one cube. Would love feedback or improvements if anyone prints it 🙌
