    There are several issues with your STL file. It is not watertight, so the object is "open" somewhere, the faces are not closed/watertight. 

     

    It is possible but not the best solution to use Blender for modeling for 3D printing. Better you use a CAD software like Fusion360, Tinkercad, Onsape, etc. They are free or free for non commercial usage.

     

    If you still want to use Blender search YouTube how to model for 3D printing and what is important. I don't use Blender so I cannot give you some advices. 

     

    If you want to rescue your current model you could try if a STL repair service is able to solve the problem.

    It would be easier with the actual .blend file...

    But the main problem are a lot of intersecting faces in the resulting stl file.

     

    It's a bit guesswork... it seems like the two inner divisions are separate cubes that are crossing each other and are touching (but not connected to) the outer walls. This will not work for 3D printing because it results in intersections and overlapping geometry.

    The whole piece is needed to be a single, manifold geometry. Don't stitch together separate parts in this way. Start with a single cube. Use only "scale", "loop cut" and "extrude" and you will get a box with a mesh topology that is perfectly suited for printing. Merge duplicate vertices before exporting - just to be sure.

     

    Something like this:

     

    Step 1 (loop cuts):

    Step 2 (extrude):

    It depends how good you are with Blender, but if you design simple objects like the one above you are much faster with a dedicated CAD software. So if you are new to Blender, check also the other applications I mentioned above. For sculpting and "creative" things Bender is the first choice for such things.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
