We’ve seen some real high quality 3D prints of items that either use existing Ikea products or repurpose them in some way. In this way Ikea serves as a design an making platform that you can add to or customize. Because Ikea is everywhere many people can use these files to add to their existing Ikea furniture. I think this is a very interesting development and am always surprised as to how many people are now designing for themselves and using Ikea in this way.
Lina & Thomas have made a lovely flower pot holder that fits Ikea plant pots.
Anders Olson has made a “Extender for IKEA LOGGA shoe rack to increase clearance to enable robotic vacuum cleaners cleaning under it.” This is a very modern extension of an Ikea design.
