**Exact dimensions.** Every file is drawn at true size with no printing tolerance. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your printer's or process's clearance before making the part.

## Notes

- A wheel Ø23.89 × 10.23 with a 90° V groove 3.2 deep around the middle; the groove rides the V of a 6 mm V-slot.
- A Ø16 bore (625 OD) runs through, with a 1 mm lip at mid-width (Ø11 hole) that separates the two 625 bearings.
- Axle: M5 through the two 625 bores.
