**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- The common bamboo skewer is Ø3 × 300 mm (12 in); the file is a plain Ø3.0 × 300 cylinder.
- Thinner Ø2.5 × 200 mm cocktail skewers and thicker Ø4 × 400 mm skewers also exist.
- At Ø3 it matches the bore of a 623 bearing and any Ø3 hole drawn in the library, which is why I use it as the crankshaft on the can engine.

## Sizes

| skewer | dia_mm | length_mm |
|---|---|---|
| standard | 3 | 300 |
| cocktail | 2.5 | 200 |
| long | 4 | 400 |

3 mm for the common 300 mm (12 in) skewer; 2.5 mm × 200 for cocktail skewers and 4 mm × 400 for long ones.
