BEST ADVICE OUT THERE!!!

So, I got one of the ChowThink rail upgrade kits for an Ender 3 and love it. Doing some routine maintenance,  it looked like it was time to switch out the good old brass Screw Nuts T8 Lead Screw to a composite https://a.co/d/7DH1w1a that seem to work fantastically to take some of the slop out. In the middle of a rebuild on another Ender rail upgrade and looking at parts for the SOVOL I ran across this as I have immaculate prints from them and confirmed that its a floating lead screw. 

So we re-designed the bracket that came with the kit allow for some movement as I was not able to remove the bearings from the original and drill them out.
