Has anyone the source for the Y axis LM8UU holder for the RepRap 2020 i3? It is not available on the google drive. I published a spacer on Thingiverse to make the Prusa Mendel i2 LM8UU holder work as an equivalent. That's what I'm using now. However I cannot find the Folger Tech STL. I have 2 of my 3 original holders and would like to make another. Any help would be greatly appreciated. It would also be an open source contribution since they haven't been published yet as far as I can tell.
