The Exomars Rover is said to be the first European rover on our neighboring planet one of the most demanding missions that ESA has ever carried out so far. He would also be the first Rover, who is supposed to search for life on Mars, not only on the surface but with the drill on the front of the rover to a depth of 2 meters. Unfortunately, technical problems caused several delays, unfortunately the start date is currently unclear.
After I couldn't find any STL files for this model, I constructed it myself in Fusion360. I use Cura as a slicer and my Creality Ender 5 as a printer. At the end of the page there is a ZIP file for free download that contains all the necessary STL files. In addition, I documented the most important construction steps in short form.
STEP 1: UNDERCARRIAGE
Parts to be printed: 6 x Wheel.stl 6 x WheelMount.stl 2 x FrontConnector.stl 2 x SuspensionRight.stl (one mirrored!) 1 x Body.stl 1 x SuspensionRear.stl
The "SuspensionRight" is required to fix the front suspension system with the body of the rover. To get the part for the left side, you need to mirror it in your slicing software.
STEP 2: BODY
1 x Drill.stl 1 x FrontPlate.stl 1 x Radar.stl 1 x RadarMount.stl 2 x SidePlate.stl
STEP 3: SOLAR PANEL AND MAST
1 x Mast.stl 1 x MastMount.stl 1 x SolarPanel.stl
The ZIP file contains all required STL files to print the ExoMars Rover Model. Feel free to use and share them as you like.
