Vape Tank Atomizer Coasters with Case

I really liked the original idea by SirTimmyTimbit of tank coasters and a holder for them. I wanted to store my pods on these as well but couldn't because the originals were flat on top. I increased the overall coaster size to 38mm by 38mm by 8.5mm. I increased the coaster holder to accommodate these as well. I then added a recessed indentation 30mm wide onto each coaster. So the overall size limit for atomizers remains at 30mm. I also shrunk to hole in the coaster for the 510 to 7.5mm. This allows the tank to be screwed into the stand now rather then just sitting in place. I still use the flat coasters for tanks that are larger then 30mm, as they can hang off the coaster and still stand up. I use my remixed versions for everything else. I printed them at .20mm layer height with ironing on for topmost surfaces.
