I loved this build

But on my Prusa at 0.30mm the sliders were just impossible to slide. Others have reported them being too tight and having to sand them. After a few hours of sanding I gave up and just cut back the size of the slider elements so that they are not a perfect fit. They slide nicely with very little wiggle room.

This is JUST the single slider - print 2 or 3 as needed with the rest of the original build (minus the original slider!)

Also the stainless bars are 3mm, NOT 4mm. And if you want to save money and cut 300mm bars to size (I went with 135mm for top and bottom, to hold full size bottles), sand them to the exact size once cut. Even a mm off is too much.
