Excellent design, thank you very much for posting these! They are a great fit on the 22L boxes we got. I resized them to be 40mm high and they are super sturdy (check http://www.thingiverse.com/thing:1844657 if you need the resized model).
Also, at least in the US, Ikea does not manufacture the clips for the bigger boxes anymore (checked in Emeryville, CA). The Ikea website confirms this (http://www.ikea.com/us/en/search/?query=samla). This is a different situation than in Europe, where they still sell them and in all sizes (cf for instance the French site at http://www.ikea.com/fr/fr/search/?query=SAMLA+Fermeture).
Thanks again for sharing your files!
