# Here you can get all your rod lengths for i3 right.
If you are using single plate model, use *italic numbers*.
"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

## Y axis
You need 2 smooth rods, 2 M10 rods and 4 M8 rods

### Y smooth rod length is sum of:
 * workarea (200mm)
 * belt assembly parts (100mm) or outer dimensions of Y bearings (100mm for Prusa3ALU-FREZOVANY-v4.dxf)
 * 40mm inside Y axis corners

for 340mm minimum. EiNSTeiN uses *400mm* rods, so I may be missing something here.
Take care they are cut exactly to the same length

### Y threaded rods (M8):
Sum of:
 * rod separation (170mm)
 * Y axis corner (20mm)
 * nuts and washers (15mm)

For *205mm*, or 210mm if you use nyloc nuts.
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.

### Y threaded rods (M10):
Y Smooth rod + 30mm, so *430mm*. May be longer.


## X axis
You need 2 smooth rods

### X axis smooth rod
is box/plate width plus 25mm, so *395* for single plate, 475 default box. May be longer.

Working area will be at most box width - 170 for single extruder and box width - 270 for dual extruder

## Z axis
You need 2 smooth rods and 2 M5 threaded rods

### Z axis smooth rod:
Box height - 50mm, so *320mm* for single plate, or 400 for default box. May be longer
### Z axis threaded rod
Smooth rod - 20mm, so *300mm* (or 380 for default box). May be longer.
