I would try any firm that sells reproductions (licensed or not)....I once went looking for feet for my Eames desk chair and a dealer (alas I can't remember which one but they were based in the Carolinas) -- was willing to send me a replacement for free.

You might try http://www.highbrowfurniture.com - I know they have replacement parts for Eames designs, but not sure about the Le Corbusier stuff, though.

Trying to make one out of Sugru would be an inexpensive option.

$55 for a set of four from Palezzetti. Google is an amazing tool. I googled "le corbusier chase parts." :)

Cassina holds the license for Le Corbusier furniture and I know they sell replacement parts. They have a show room in NYC or you can call them.

Thanks for jogging my memory.

Lost mine too, and didn't think to ask here, so now I will buy the real things, but if you want a cheaper solution, I stuck some of these on it, http://www.amazon.com/gp/product/B000KKXGAQ/ref=oh_details_o01_s00_i00 and it looks kind of cute - and I love being able to slide it around on the wood floor!

were to find just one small part for kartell roller dimmer? http://www.voltexdesign.com/dimmer-for-bourgie-kartell-pid686.htm

I don't need to replace the whole dimmer, but a smallish stick (?) that keeps the roller is palce
