Made a small part to clamp the bearing under the bed. It was an attempt to reduce the griding/ratteling sound when the Y-axis moves fast. I think it helped a little bit.
It can surely be debated if it is needed or any good but anyway; here it is.
Independently almost identical solutions to the same problem, that has mean that its a good design
Yours seem to have a better grip on the bearing but on the other hand it needs support material.
