Summary

This is part number 21399-26, which is a plastic bushing for the upper wheel mounting block. The bushing on my saw disintegrated yesterday, so I measured the fragments and made this replacement in OpenSCAD. I designed it to be a tighter fit than the original, so you might have to file it down a tiny bit (or file away any blobs or burrs on the block that it goes into).
