Martians coming home! One formfactor based Pyramidal martian colony design.

Hey friends!
This is a martian colony design for a #MakerBotMars challenge.
As we all know, pyramids in Egypt were built by martians. Now we are going to pay same for mars - build pyramids on it!
Concept is based on ideology that pyramids are awesome structure which is very close to natural forms and gives you a list of bonuses when build from smaller blocks:

• Only two different block form factor are needed
• Pyramidal design is extremley durable against all enviromental effects
• Modular construction allows to start with small steps
• Damage proof - if one block is damaged, all others may be sealed, like a submarine!
• Damaged blocks may be replaced, even if they are deep inside of the construction, with proper rail system.
• Modules can have any inner configuration you need
• Pyramidal blocks are easy to print(you wont need that ugly mounting system on mars)
• Outer blocks at big buildings like living blocks may be filled with martian soil to absorb radiation(gives you underground building bonuses without need to dig in)
• It gives you beauty of simplicity
  Pick few of these two bricks and try yourself!
  %%%Remember to scale the model so rails are printed good enough!!%%%
