Nespresso Vertuo (2014) Oversized Cup Holder

My family likes caffeine… the Nespresso cup holders are laughably small and unstable. I made a wider version for larger mugs that resists tipping during the machine's cycle. 

To achieve the grid pattern:

With Prusa Slicer: 

Download the two models and print separately. Both files have two bodies inside of one object and once loaded in Prusa Slicer you'll need to separate the bodies into individual parts. Keep the orientation of each part with respect to each other and then change the inner volume/part to a modifier and adjust the top and bottom layers to 0. Adjust the infill as desired. 

With Bambu Studio:

Step-by-Step: Separating Overlapping Bodies & Using a Modifier in Bambu Studio

🧩 1. Import Your STL File

Open Bambu Studio.

Drag in your .STL file that contains two overlapping bodies.

If the file is a single mesh but has two manifold overlapping bodies, Bambu Studio often treats them as a single part unless you separate them.

✂ 2. Separate the Bodies

Right-click on the imported model in the object list or on the bed.

Choose “Split Selected Model into Parts”.

Bambu Studio will separate each disconnected mesh shell into its own part.

Now you should see two items in the object list — likely one is the main part, and one is the piece you’ll turn into a modifier.

🧱 3. Identify the Part to Use as Modifier

Click each separated part to visually inspect which one should be the main printable part, and which one will act as the grid (modifier).

🔄 4. Convert One Part to Modifier

Right-click on the part you want to use as the grid modifier.

Select “Change to Modifier”.

It will now appear nested under the main model in the object list as a modifier.

🧩 5. Set Modifier to Reveal Infill Grid

Click the modifier in the object list to open its settings panel on the right.

In the modifier's settings:

Go to Per-object Settings.

Enable "Top Solid Layers" and set it to 0.

Enable "Bottom Solid Layers" and set it to 0.

Optionally, you can also:

Change infill pattern to Grid or Gyroid.

Set a high infill density (e.g., 100% for full visibility or 15–25% for sparse structure).

This will make the area under the modifier show only infill — a "grid" look — without top or bottom layers.

🖨 6. Slice and Preview

Hit Slice.

Use the Preview tab to visually confirm that:

The main part slices normally.

The modifier region has visible infill with no top/bottom solid layers.

✅ 7. Print!

Save the G-code or send it to your Bambu printer.

You’ll get a model with a grid-exposed area exactly where the modifier overlaps the main model.
