A couple of months ago I was cleaning my Gen and discovered my coil was completely burned out. Recently I bought a new coil so that I could vape again. When I reassembled everything I realized I couldn't find the mouth piece. I've looked online for replacement parts but I cannot find it. In the picture below I've circled what's missing. To be clear it is only the plastic components that I am missing. I have been using prestik to cover refill hole in the mean time. If anyone reading this could help point me towards a store that would sell the missing components that would be much appreciated.
