   1 # Here you can get all your rod lengths for i3 right.
   2 If you are using single plate model, use *italic numbers*.
   3 "Default box" is made of 6 450mm boards and one that is 2 * board thickness longer, see http://78.47.92.212/i3_documentation_pics/06-frame.md.html

   5 ## Y axis
   6 You need 2 smooth rods, 2 M10 rods and 4 M8 rods
   7
   8 ### Y smooth rod length is sum of:
   9  * workarea (200mm)
  10  * belt assembly parts (100mm) or outer dimensions of Y bearings (100mm for Prusa3ALU-FREZOVANY-v4.dxf)
  11  * 40mm inside Y axis corners
  12
  13 for 340mm minimum. EiNSTeiN uses *400mm* rods, so I may be missing something here.
  14 Take care they are cut exactly to the same length
  15
  16 ### Y threaded rods (M8):
  17 Sum of:
  18  * rod separation (170mm)
  19  * Y axis corner (20mm)
  20  * nuts and washers (15mm)
  21
  22 For *205mm*, or 210mm if you use nyloc nuts.
  23 If your rods are cut right to the size (and are all exactly the same length) you will have easier time getting the frame right.
  24
  25 ### Y threaded rods (M10):
  26 Y Smooth rod + 30mm, so *430mm*. May be longer.
  27
  28
  29 ## X axis
  30 You need 2 smooth rods
  31
  32 ### X axis smooth rod
  33 is box/plate width plus 25mm, so *395* for single plate, 475 default box. May be longer.
  34
  35 Working area will be at most box width - 170 for single extruder and box width - 270 for dual extruder
  36
  37 ## Z axis
  38 You need 2 smooth rods and 2 M5 threaded rods
  39
  40 ### Z axis smooth rod:
  41 Box height - 50mm, so *320mm* for single plate, or 400 for default box. May be longer
  42 ### Z axis threaded rod
  43 Smooth rod - 20mm, so *300mm* (or 380 for default box). May be longer.
