This is the last evolved version of Akiyuki’s Archimedes Screw module. The path of the balls is surprising at first sight but reveals quiclkly to be really well thought. This is for me the smartest archimedes screw from the series.

Hello DuKtine,
I think it’s “Hose, Ribbed 7mm D. 12L (Item No: 78c12)”
I’m not fully sure about the length (I would say 12L). Indeed I can see that these corrugated pipes are missing from the parts list
Thanks for your quick answer.
Yes, they are missing from the part list. That’s the reason of my question. I was no sure for the length.
Hello DuKtine,
Courbet answered this question on EuroBrick forum:
All 13 purple ones are 12L, and the 12 black ones for the screw are 14L.
Other black ones are needed of various lengths for the output ramp (1x8L, 1x11L, 2x15L, 2x17L). Some are difficult to find at those lengths but it’s easy to modify the ramp to use whatever lengths you got using pins, axles, pins joiner round, etc.
A big thanks to him for his answer

Thanks to you turbopolofr and to Courbet.
My son will soon be able to build the Archimede GBC !
Does anyone have the reference for the black and purple hoses ?
