I think I read it wrong and your wanting the sleeve to go over the nozzle then use a knife. You have to mind and use material thickness so your inside of your sleeve will be the outside of the nozzle. I see your tip has 14mm diameter at the top. if you have a 1mm wall then it will obviously be 12mm inside that then gets cut. Send me the dimensions that you want the finished nozzle to be.
