Saw these $3 flip-flops and an idea popped up.
The sole seemed just the right thickness and firmness to hold our little bottles securely.
I used spade drill bits except the 30ml holes were a hole saw. Doesn't cut perfectly clean,
I stuck them in the freezer and they got stiffer but still didn't drill cleaner.
1Dram / 4ml / 1/8oz glass vial = 1/2"
2Dram / 8ml / 1/4oz glass vial = 5/8"
3ML LDPE bottle = 5/8 or 11/16"
5 & 10 ml ldpe and PET bottles = 3/4"
30ML glass = 1 1/8"
30ML LDPE = 1 1/4"
Sizes are for drill bits - in the rubber they will make a hole smaller than they would in wood.
An 8ml flavor vial is 1/2" in diameter but the 5/8 drill makes a hole that seems just right - tight enough that you
can uncap/cap it one-handed but you can push it in or pull it out of the foam without upsetting its neighbors.
I don't have a 1 1/8 drill and the 30ml glass bottles are loose in the hole from 1 1/4 saw. 1" is too tight but a sharp
steak knife could enlarge it pretty cleanly.
