I think it's a pretty cool, unique design to move blocks large amounts of spaces!
Features:
• INFINITELY EXPANDABLE!
• Fast! Moves blocks at whopping 5m/s! (Retracts at ~3m/2)
• 4x3x1 footprint per module!
• Fits in ceilings and walls!
Materials (per module):
• 4 Observers.
• 2 powered rails OR 2 activator rails.
• Any solid block.
• 2 sticky pistons.
• 2 repeaters.
Edit:
The original title was "Infinitely Expandable Piston Extender", but months after learning otherwise, I have changed it to reflect this actually being a block conveyor. I don't think I'll change the thumbnail.
