A bathroom holder that actually fits
Toothbrushes, electric toothbrushes, razors, cups, toothpaste and personal care products rarely have standard dimensions. That is why ready-made bathroom organizers often only partly fit the items you actually want to store.
With the Vuolti Bathroom Holder Generator, you define the dimensions yourself. Adjust the overall size to the available space and choose how many openings you need and how large they should be.
The construction and mounting can also be adapted to the intended use. This turns a simple holder into a model configured for your own bathroom or a specific item.

Every value in detail
Every value in the generator and what it does. Open the one you are about to change.
Create openings that fit your items
The openings in the top plate are one of the most important parts of the generator. Choose how many openings you need and define their diameter.
If all items are similar in size, a single shared diameter can be used. If you want to store an electric toothbrush, a razor and a smaller brush together, different opening sizes may be more useful.
The oval factor lets you change an opening from circular to a more elongated shape. This is useful for objects that do not have a round cross section.
An adjustable lead-in chamfer can make objects easier to insert while also creating a smoother edge around each opening.
Fit the holder to your available space
In addition to the openings, you control the overall width, depth and height of the holder. This makes it possible to design around a specific area beside a sink, a narrow section of wall or an existing bathroom cabinet.
The vertical corner radius can also be adjusted, allowing you to choose between a more rectangular or more rounded appearance.
The generator displays both outer and inner dimensions so you can better understand the usable space inside the holder.
Configure the back and wall mounting
The holder can be configured for mounting on a wall or another vertical surface.
For screw mounting, the mounting area and screw hole diameter can be adjusted. A countersink can also provide space for the screw head.
Depending on the configuration, a flat back can also be combined with a suitable adhesive mounting solution.
Always consider the surface, weight and expected load. For bottles or multiple heavy items, mechanical mounting may be more appropriate than adhesive tape.
Open or closed front
The front can be configured to suit the intended use.
An open front provides easier access and can help moisture escape. A more closed design can retain smaller items and create a more enclosed appearance.
The front thickness can also be adjusted.
Floor and drainage
Bathroom organizers regularly come into contact with water, so the floor design can be important.
A closed floor retains water inside the holder. An open or drained configuration can instead allow water to escape.
Opening size, web width and fill height can be adjusted to create a floor suitable for the intended use.
For permanently damp environments, the filament choice should also be considered.
Recesses below the openings
Optional recesses can be created below the openings in the top plate. Their depth and oversize can be adjusted.
These recesses can provide additional clearance below an opening or help accommodate specific object shapes.
Add hooks underneath
The Bathroom Holder can also include hooks underneath.
Choose the number of hooks and adjust their position, width, depth and drop. They can be used for lightweight items such as small towels, hair ties, cables, brushes or other bathroom accessories.
This allows one model to combine a top holder with additional hanging storage.
How to choose the right hole size
Measure the object where it will pass through the opening. Do not automatically use exactly the same measurement as the hole diameter.
3D printers and materials can produce small dimensional differences. Some extra clearance also makes an object easier to insert and remove.
For example, if an item measures 24 mm in diameter, a slightly larger opening may provide a better fit. The ideal amount of clearance depends on your printer, material and desired fit.
- Measure the object at the actual support position
- Leave some clearance for easy insertion
- Test very tight fits before printing the full holder
- Consider width and depth separately for oval objects
- Use different hole sizes when storing different types of items
Examples of custom bathroom holders
Toothbrush and razor organizer
Use different opening sizes for toothbrushes and razors so several types of items can be stored in one holder.
Bottle and personal care holder
Larger openings can accommodate small bottles and containers. Adjust the overall dimensions around the products you want to store.
Family bathroom holder
Create a wider organizer with multiple openings for toothbrushes or electric toothbrushes belonging to different family members.
Wall holder with hooks
Combine screw mounting with additional hooks underneath to create extra storage beyond the openings in the top plate.
Custom configuration for someone else
Create different sizes and configurations for family or friends, each sized to their own bathroom fixtures.
How the Bathroom Holder Generator works
- Set the overall dimensions.
- Adjust wall and back thickness.
- Choose the number of top openings.
- Set opening sizes and shapes.
- Configure the front and floor.
- Set the desired mounting options.
- Add optional recesses and hooks.
- Check the model in the 3D preview.
- Review print size and estimated material usage.
- Generate the STL and prepare it in your slicer.
No CAD required
A custom bathroom holder can be designed manually in CAD. Once you add multiple openings, different diameters, rounded geometry, drainage areas and wall mounting, however, even a simple holder can become a much more involved modeling task.
Vuolti handles this repeatable geometry for you. You set the parameters and the generator creates the model.
CAD may still be the right choice for highly specialized engineering projects. For a functional holder with custom dimensions, the generator is designed to make the process much faster.
Why not just scale an existing toothbrush holder?
Scaling an existing STL changes every part of the model at the same time. If you increase a holder by 20 percent, wall thickness, screw holes, hooks and all openings also become 20 percent larger.
That is rarely what you actually want.
With a parametric generator, you can increase only the width, change one opening diameter or add another position while keeping unrelated dimensions under control.
For functional 3D printed parts, that is a major advantage.
3D printing tips
- Check overall dimensions in your slicer before printing
- Test critical opening diameters when a close fit is required
- Choose a material suitable for humidity and temperature
- Use sufficient wall strength for wall-mounted designs
- Check hooks and overhangs for required supports
- Verify large models against your printer build volume
Will it fit your 3D printer?
You can enter the available build volume of your printer in the generator. This helps you check whether the configured model fits within your maximum printable dimensions.
This is particularly useful for wide holders with many openings.
Which material works well in a bathroom?
Bathrooms can be warm and humid for extended periods, so material choice should match the environment.
PLA is easy to print and may be sufficient for many dry applications. For permanently damp or warmer locations, materials such as PETG or ASA can offer advantages.
The right material depends on temperature, moisture, mechanical load and the capabilities of your printer.
Why use Vuolti instead of downloading an existing model?
There are many toothbrush holders and bathroom organizers available as ready-made STL files. Often one detail makes them unusable: the electric toothbrush is too wide, the razor does not fit, one position is missing or the entire holder is too large for the available wall space.
Vuolti starts from the opposite direction. Instead of adapting your needs to an existing model, you create the model around your requirements.
The result is a functional part whose dimensions and configuration you control.
