Dual bottle NOS system

Multi part fake Dual bottle Nitrous Oxyde System with bottles, valve, pipes and “missile switchs”.

All parts can be printed without supports (except main “piping” system that requires some supports near bolts: Gcode file has custom supports).

Pictures show models printed on MK4 with firmware shipped with printer and 0.4mm nozzle.

To save print time and filaments, bottles were printed:

• with variable layer height, to have a nice and smooth finish on top,
• “Lightning” fill mode to save some filament,
• 4 perimeters were used to have sturdy bottles.
  (you can use 2 or 3 perimeters, it works)
• Really, bottles don't need classic filling (rectilinear or grid).
  Additional perimeter and lightning fill give good result.

Additional information:

• “metal” parts printed with Prusament Pearl Mouse PLA,
• “bottles” printed vertically (Height around 20.5 cm, so might fit on a Prusa MINI) with Amazon Basic Blue Silk PLA,
• “Missile switch covers” printed in Jayo Red PLA,
  (Would not recommend it, color is quite fade and looks bad)
• “Valve” printed in Prusament Gentleman Gray PLA,
• “NOS stickers” purchased on AliExpress,
  (6x7 cm metal look sticker, around 1.9 €)
• “Pipe” and bottle fits together. Additional glue required to keep them in place,
• Red missile switch covers have to be glued or screwed.
• Currently, valve has to be glued to the piping system.
  I am not very satisfied by this so I am working on a V2 version where the valve can be rotated and fixed by a single screw.
• On the “main piping” part, there is a 0.2mm margin of tolerance on the main valve axis and bottle holes
• Main valve axis can accomadate a screw (up to 2.8 mm diameter)
• “Optional Screw” fits the 2.8mm hole in the “Main piping” (any version) part.
  Can be glued inside the hole so that the “valve” can rotate freely around its axis.

Two options

• Print “Main piping (no switchs)” part, made without any “missile switchs”.
  You can add missile switch bases using two parts “Switch base” by screwing or gluging them
• Or print “Main piping + Missile Switchs” part.
  Missile switch bases are integrated with that part.
