Although design is pretty good, the size I mean height of the tubes which could be at least half shorter, causes it prints 12 hours :O If you would be that kind and make one short tube similar to the “tube left” (I mean that opened one tube) it would be awesome and significantly shortened the whole printing.

@JacekTC_229006 If I make the tubes smaller, it won't be so durable, I've been using it for 3 years without problems, I know that a lot of material goes in and the printing time is quite long, but I wanted to make a solid design
I'm not saying that lid is impossible to 3d print, but it is very very unlikely to work. I tried once just to see and yeah, it's not really feasible. Tons of sharp unsupported corners is just not a good idea.
