Boxed style Frame Style
In the future this page might contain a tutorial until then a tutorial for the boxed frame style prusa i3 by Kliment: http://78.47.92.212/i3_documentation_pics/

Single Sheet Frame Style
There is no tutorial for the Single Sheet Frame style Prusa i3 however the X axis, X cariage and Y frame and bed are mostly the same.
JBFromOZ - preparing to build an aluminium frame prusa i3.
Rod lengths are listed here http://titanpad.com/bU77NESnMC.
Prusa i1/i2 smooth rod lengths should be usable for an i3 single-plate reprap.
Instructions on the github say to RP each part in the single-plate folder. I believe this instruction applies to the box frame version only, some items need more than 1 copy.
It is not yet 100% clear which extruder to use, there is a dual extruder and a compact extruder in the branch though neither looks complete. there is also a Greg's adapter in the /mini/extruder/greg-wade folder, it uses the nuts_and_bolts.scad which needs to be copied to the openscad library folder.
I am planning to use a MGS extruder with a Nema17 stepper, designs from Sound are shown from his i3-unterwelt branch
Y PCB Aluminium frame is connected to LM8UU's with zipties, no RP parts required (as per nateplate style attachment)
