While investigating the genealogy of some Prusa i3 printed parts, I was unable to find any OpenSCAD source file for the various printed parts of the i3 Rework. Now, this is unfortunately in clear violation of the GPL license under which the original parts were released. Until RepRap France comes clean and publishes their OpenSCAD sources or other source material and provide proper attribution for the printed parts of the i3 Rework, it cannot be considered GPL-compliant (as they claim). To all effects they have stolen the IP from others and decided to make it proprietary. :-(

With all the forking of projects we have in our community, we need to do a better job of outlining what makes this fork different than the original. Could someone who knows put details on what makes the Prusa i3 Rework different than the original Prusa i3?

There is some information (in French) on the github page, here is a quick-and-dirty translation:
Improvements with respect to the original version:
* Extruder parts modified to support a Magma Hotend.
* Changes to the "Fan Duct" to achieve better cooling of the Hotend.
* Changes to the "Y Corner" to improve stability.
* Changes to the "Y Idler" to add a system for adjusting the belt tension.
* Changes to the "X End Idler" and the "Y Motor mount" to support endstops (limit switches).
* Updated the "X End Idler" to support a 624 bearing.
* Adding a "Z Endstop holder part" to support the Z-axis endstop.
Note that "original version" here refers to the original Prusa i3 Einstein, itself a variant of the Prusa i3.

is there any file for the frame?

I believe that is the aluminum single plate frame design by Josef Prusa and available commercially from a number of vendors worldwide.
Not only commercially, but also available as DXF file in "vanilla" repository (file name: alu-frame.dxf) - Xoan Sampaiño (talk) 23:31, 20 November 2014 (PST)


Hi all, sorry about the latency and this issue, we just added the STEP sources for simplify any modification. Unfortunately we do not have any OpenSCAD sources. We will try to be more reactive next time (and check more often this page I guess), do not hesitate to contact us if needed.

what package did you use to do the step files?--Thejollygrimreaper (talk) 04:15, 21 April 2015 (PDT)

First of we never used Open Scad to do design the Rework version of the Prusa i3 but a well-known engineer software we are in ease with. The package is AP203. No files have been looted en converted, all of them have been re-drawn (that is why we call it Rework) even the extruder have been re drawn from scratch (you can check the hotend fix which is different from the one of ch1t0). So if we have anything to change let us know by email. The DXF file is exactly the same as Josef Prusa (excepted the brand watercuted on the frame) We sincerely did this job thinking it was enough to be "open source", and frankly speaking the debate to know if step and stl files are open or not, was not really in our mind.
