I scaled the plans and discovered one of those faux paint bottles is actually the diameter of the lights on a Dalek just needs cutting to size.
So ironically I bought 2 of these small bottles of paint from the local craft store. $1 for 2. This is the same craft store that was selling the exact same size blank bottle for $1.50 each.

Got home and got rid of the paint out of the bottle, I then started to soak the label in an attempt to remove it and the glue from the bottle.

OK the label did not come off as cleanly as I expected but still a saving of $2.00 here,
