Eccentric Spacer
When rotated, eccentric spacers accurately position V-wheels on a plate such that they can firmly engage V-slot aluminum extrusions. They are only used on wheels on one side of an extrusion. Adjustments are made by using a 8mm wrench on the spacer itself.

Component tests
| Test | Description | Target | Tolerance |
|---|---|---|---|
| Hex size | Fit an 8mm wrench on the spacer. | Wrench should fit spacer | N/A |
| Engraving | Inspect the part for a 6mm engraving on the side with the shortest distance to the bore. |
Engraving is in correct location | N/A |
| Length | Measure the spacing that the spacer will provide using calipers. | 6mm | +/- 0.2mm |
| OD | Measure the outer diameter using calipers. | 7.1mm | +/- 0.05mm |
| ID | Measure the inner diameter using calipers. | 5.1mm | +/- 0.1mm |
| Material | Ensure the material is aluminum or stainless steel and will not rust by holding a magnet to the part. | Aluminum or stainless steel (no magnetic attraction) | Weak attraction to stainless steel is permissible. |
