Did not try the same one. I'm not convinced it will even work, don't want to waste money on this stupid idea, so I print one to see how terrible the idea was.
Linear bearing LM8UU - Igus Style by 3DRAP

I was surprised it actually works, it stuck in the beginning, but after multi-round slide along the rod, it is actually pretty smooth. I use it on Anet A8, which came with crappy linear bearing, the printed one is much smoother. Then I see this

The Spiral vase linear bushing work as good as Igus Style one, but much lighter, and I followed the author's recommendation on facebook to print Bearing blocks to replace Anet A8 stock full metal Bearing blocks, these two mods greatly reduced the weight for Y axis.

I did lube them for the first time after they slide smoothly on rod, probably unnecessary, did not lube them after that. Although I don't like the idea of replace the metal linear bearing with plastic one, but I have to admit it actually works better than Anet A8 linbearing, not sure if it is better than CTC one. I did not replace all my printer bearing with printed one, not sure if plastic one will last long.
