The ikea NATTGIBBA laundry basket has a major flaw. After a short time the fabric used to create the two separate compartments loses its elasticity, comes off and always falls inside the basket every time the basket is filled or emptied. It makes you want to change the laundry basket.

I made blocks (file block V1) to keep the fabric in place and avoid the annoying problem.

I also made a lock (file block V2) to hold the laundry hamper lid in the open position.
