Baddeley B2V2 Lower Rear Panel w/Ventilation Slots

On the Baddeley B2V2 build, I mounted my Sabertooth motor controllers in the three vertical cavities found in rearPocket.stl.

Since motor controllers are prone to generating heat, I also wanted to provide additional air circulation and ventilation. To do this required modifying both the rearPocket.stl piece and the corresponding outer skin panel, LowerRearPanel.stl.

Modifying rearPocket.stl

Using PrusaSlicer, I added some primitive shapes as negative volumes to effectively remove some material and open up sections of the pocket to allow for improved air circulation around the motor controllers. I arranged my cuts like this:

You can do the same or similar if your slicer offers similar functionality. If you are using PrusaSlicer, I have included the project .3mf file (RearPocket_Modified.3mf) that I used in the files section below.

UPDATE: I have included an .stl file of the modified rear pocket that I used for my initial build in case you don't want to make the changes yourself. Additionally, there is a much more intricate modified rear pocket now available within the Baddeley B2V2 fileshare that includes mounting points for the motor controllers as well as wiring guides for a neat appearance.

Modifying LowerRearPanel.stl

The modification for LowerRearPanel requires a more detailed cutting shape - one that cannot be achieved using primitive shapes. So I created a model of the slots themselves to use as the cutting shape.

UPDATE: I have now added .stl files for both the “Angular” version of the lower rear panel (as originally provided in this mod) as well as the newer “Clean” version of the panel with the ventilation slots already applied. This means you do not have to make the cuts yourself.

I will continue to provide the slots that can be used as a negative cutting volume in case there are future skin variations released, or if you prefer to orient them differently than I have.

Customizing the Stock Panel Yourself:

Import B2PanelSlots v2.stl as a negative volume within PrusaSlicer and use it to cut the angular ventilation slots in LowerRearPanel.stl. As above, I have also included the PrusaSlicer .3mf project file that I used (LowerRearPanel_WithSlots.3mf).

Note that both the left and right slots are included in a single cutting volume file. This makes it easy to position both precisely if you are able to print the one-piece lower rear panel. If you need to print the cut version of the panel, you should still be able to position the slots accordingly for each piece of the panel.
