UPDATE: 12/22/2017 - Fixed the Frame Thickness to 6.25 mm, which was originally incorrect.
UPDATE: 1/14/2018 - Added new Heatbed Cover. Found in V3.
UPDATE: 2/14/2018 - Added the STEP files for the R2 parts.
UPDATE: 2/17/2018 - Added the SolidWorks Assembly with the R2 parts. Added the "Prusa Research" text to the Stepper Motors and heatbed to make it look more realistic.
UPDATE: 7/8/2018 - Added the Heatbed cover (no screws version), LCD Knob, and PSU Cover to the STEP files. Added them to SolidWorks Assembly in version 3.04
UPDATE: 8/2/2018 - Added the R3 version with the new extruder. Note that the extruder STEP files are now in the Prusa GitHub (I still will upload them here though to keep things together)
NOTE - I have a new SolidWorks Assembly of the Multi Material Upgrade 2.0 on a separate page: https://www.thingiverse.com/thing:3080920
This is a SolidWorks Assembly of the Original Prusa i3 MK3 by Prusa Research.
Since the printed parts on the GitHub are only in SCAD and STL format, this limits what you can do with the parts.
Therefore, a few users on the Prusa Forum and I took the SCAD files and converted them to STEP files using FreeCAD. When they were imported, much of the cutting commands were lost, so I had to manually select the bodies and subtract them.
Made in SolidWorks Student Edition 2017-2018
I have also posted the assembly to GitHub and GrabCAD:
I have published this under the same Open-Source Licence as the GitHub licence (GNU-GPL) and I want to give credit where credit is due:
PR Forum members themzlab, dan.d4, martin.m25 for helping convert some of the more difficult files,
Neil Rosenberg from UNC-Asheville Mechatronics for his teaching in SolidWorks while I was in FRC. Also, for providing me with a SolidWorks Assembly of another 3D printer. (which contained the E3D hotend and the Bearings I used)
Josef Prusa and his team at Prusa Research for creating this amazing machine in the first place.
NOTE: if you have a certain format that you need this in, post a comment, and I might be able to add it to the files, if SolidWorks allows!
Using FreeCAD, I was able to convert the OpenSCAD files into STEP, and then SolidWorks format.
