حافة Ø 25/4 مم، مع فتحة جانبية

Machined the profile hole to tolerance exactly as specified, so the 25/4 mm rim seats without any play on the shaft. Feels solid in hand and the finish is clean with no burrs. Exactly what I needed for the build.

The profile hole fit perfectly on the 4 mm shaft I was working with, no wobble at all. Diameter measured right at 25 mm, which matched the spec sheet exactly. Solid little component if you're building or repairing something that needs this exact size.

Wasn't sure a single rim part would matter much, but the 25 mm diameter fit my build exactly and the profile hole let me key it in without any wobble. Machined cleanly, no burrs on the edges.
