I have reviewed the measurements and everything looks good to me (although I'm using a cheapo caliper). It would be great if someone else could also check them.
Thanks for checking! You are the second one, but I wasn't too confident in the last persons measurements. One dimension I don't think I have written down on the spec sheet, is the OD of the tube.
Kind of nice to see that I can reach tolerances of 0.002" with this printer.
Just received the bearing, and it's a perfect press fit... Just able to press it in by hand. As long as the ID of the tube is good, and all the dimensions for the keyway and screw holes are good. This should engage the two really well. This also means I'm going to be able to ship it assembled, with this nuts captured inside.
