Here is a Romulan ale bottle (laser cut version) inspired by Ron design https://www.thingiverse.com/thing:3372664
I used 200mm long and 90mm outside diameter perspex tube (84mm inside diameter). For the neck I used 70mm lond and 28mm outside diameter tube.
Rest is laser cut in 5mm perspex (it will fit on A3 or 2x A4 sheets).
The bottom of the bottle contain 3x 90mm discs and 3x 84 mm discs. The neck contains 8 various diameter discs and when you will assemble it together you should leave 4-5mm gaps between each disc.
The romulan logo is engraved and then painted with gold acrylic base paint.
To glue it all together I used gorilla super glue. If you like to use to keep actual alcohol inside you would have to find food grade glue for perspex. At the moment it's just used as a prop.
