The ice cream exist out of 2 parts: the cone and the cream. For the cone you have the option for the wireless or wired version. Here are the links to the led pucks i used: wireless version: https://eu.store.bambulab.com/collections/makers-supply/products/remote-controlled-16-color-rgbw-puck-lights wired version: https://eu.store.bambulab.com/collections/makers-supply/products/led-lamp-kit-001 , also in the pictures you will find the dimensions of the puck if you like to buy them somewhere else. both cones and cream need printing supports and i recommend concentric top layer for the cream.
