2PCS Window Sash Clips

Hi Everyone, As some of you have read my thread about sash window clips which could be bought via ebay but not to Nissan's own design & when using another version of nearly the same thing I've noticed that we would be adding another 2.2cm to the lifting mechanism so the windows might not fully go down enough in the door but I don't know this yet. However are there any of you who have the use of a 3D printer & could you print off these clips instead? I'm surprised that if these clips or any other parts from nissan are not available, so why is no one re-making them. When I belonged to the 2CVGB Club they had lot spare parts made for them from body panels, engine parts, rubber door seals to plastic door catches. Yours Peter0003
