This model is a replica of the original IKEA designed by Inma Bermudez, I did it in fusion360 after accurate reverse engineering of the design. The few differences (in the inside, so invisible) are for the printability of the model.
The attached 3mf is a saved project from Prusa Slicer, with 2 modifiers for a better slice and the plain model.
