List of Common Spare Parts

[ResIpsaLoquitur]

Has anyone ever compiled a list of what you can expect to get spares of in any given Lego set? It used to commonly just be small parts like single 1x1 pieces, but I'm surprised what I'm getting spares of (and how many of them I'm getting) in this year's Advent Calendar.

Here's what I've usually seen as spare pieces:

- 1 x 1 tiles (round or square)

- 1 x 1 plates (round or square)

- 1 x 1 cheese slopes

- Technic pins (any length)

- 1 x 1 x 1 bricks (not often, but it happens)

- 1 x 1 x 1 cylinders

- 1 x 1 x 1 cones

- Minifigure tools (i.e., wrenches, handcuffs, weapons)

- Minifigure clothes (usually caps, fire helmets, scarves, visors)

- Flames

- Fire extinguisher nozzles

What other bonuses tend to be out there?
