screwed linear bearing

Never underestimate vase mode again!

While I want to print again LM8LUU to test my new Ender 5 bed, I seek many other option including vase mode one. But I still want the spin / screwed type then found one with OpenSCAD code. With double wall hack I already learned I try to make it vase mode and double walled. Testing it with my odd 8.3 rods I found it strong and nice sliding and become my favorit now :)
