Adhesive Tube & Bottle Holder Generator
Create a stick-on cup that fits your tube or bottle exactly. Choose a round, oval or rectangular pocket, set the clearance and enlarge the adhesive face with a wider, taller back plate. No drilling, no screws – Vuolti generates your STL right in the browser.

A holder for exactly the tube that keeps falling over
Bathroom products come in every shape: round toothpaste tubes, oval shampoo bottles, flat shower gel bottles, deodorant sprays and shaving foam cans. Off-the-shelf holders rarely fit – too loose and the bottle tips over, too tight and it won't go in.
With the Vuolti Adhesive Tube & Bottle Holder Generator you enter the size of your tube or bottle and get a cup that holds it upright on the wall. The back is one flat face across the full width of the holder, made for double-sided tape on tiles, glass or mirrors.
Starting values for typical bathroom products get you going. They are guide values only: measure your own tube or bottle where the holder will grip it.
What you can customize

Every value in detail
Every value in the generator and what it does. Open the one you are about to change.
As much adhesive area as possible
A stick-on holder holds only as well as the area that touches the wall. That is why the back is not round like the cup but flat across the full width of the holder. The cup is round or oval at the front; at the back there is one continuous adhesive face.
If that is not enough, the back plate widens the holder at the sides and extends it upward. With the default values that adds up to about 31 cm². The plate only grows sideways and upward, never below the floor – so the holder sits flat on the bed and needs no support.
The generator shows the adhesive area in cm² and suggests how many 19 mm tape strips of what length fit on the plate. Small areas and large, heavy bottles trigger a notice.
Round, oval or rectangular
Round pockets fit toothpaste tubes standing on their cap, deodorant sprays, shaving foam cans and pump dispensers. Oval pockets fit shampoo bottles and tubes with a wide flip-top cap. Rectangular pockets with an adjustable corner radius fit flat shower gel bottles.
For the oval shape, the outer wall is a true offset of the pocket, not a larger ellipse. That keeps the wall equally thick all the way round.
Drain hole and sloped floor
In a bathroom, water ends up in the cup. A drain hole in the middle of the floor is therefore on by default, with an adjustable diameter.
Optionally, the floor can fall slightly toward the drain hole. Water then runs to the middle and out instead of standing at the edge. You set the drop at the edge in millimetres. Without a drain hole, the slope runs to a point in the middle. The default is a flat floor.
For tubes whose cap should stick out underneath, there is also an open bottom.
Test the fit first
A holder that is too tight is annoying every day; one with too much clearance wobbles. Before you print the whole holder, you can download a short ring with exactly the same pocket. It prints in a few minutes and shows whether the tube or bottle goes in well.
Print it upright
The STL comes out the way the holder hangs on the wall: floor on the build plate, back vertical. That makes the adhesive face one continuous flat wall without support.
With the sloped floor, the inside gets a shallow incline that also prints without supports. Still check the slicer preview before every print.
Material and tape for the bathroom
For the bathroom, PETG or ASA are a good starting point because they cope with moisture and warm water better than PLA.
With tape, preparation matters at least as much as the tape itself: degrease the surface with alcohol, let it dry, press the holder firmly and ideally wait a day before loading it. Acrylic foam tape bridges small irregularities and suits smooth tiles, glass and mirrors. On grout lines, textured plaster or wallpaper, tape holds far less well.
Why not just scale an existing STL?
Scale up a ready-made tube holder and the walls, floor and back plate get thicker too – and a round pocket never turns oval.
Vuolti rebuilds the geometry from your measurements. Pocket, clearance, wall thickness and adhesive area stay independently adjustable.

Frequently asked questions
Which tubes and bottles does the holder suit?
Anything that stands upright in a round, oval or rectangular cup: toothpaste and cream tubes, shampoo and shower gel bottles, deodorant sprays, shaving foam cans or pump dispensers. You enter the size yourself.
Do I need to drill?
No. The holder is mounted with double-sided tape. The back is a flat face made for it.
How do I make the adhesive area larger?
With the back plate: it can be wider on each side and taller than the cup. The generator shows the area in cm².
Which tape should I use?
Acrylic foam tape is a good starting point for smooth tiles, glass and mirrors. What matters is a degreased, dry surface, firm pressure and some waiting time before loading.
How much weight will it hold?
There is no universal figure. It depends on the tape, the surface, the preparation, the adhesive area and the material. Test your combination before you put a full, heavy bottle in it.
How does water drain?
Through a drain hole in the middle of the floor. Optionally, the floor slopes toward the hole so no water stands at the edge.
How much clearance should I set?
About 1 mm per side is a good start. Use the test ring to check the fit before printing the whole holder.
Which material makes sense?
PETG or ASA, because they cope with bathroom moisture and warmth better than PLA.
Do I need support material?
No. The holder prints upright with its floor on the build plate, sloped floor included.
Do I need CAD experience?
No. Enter your dimensions and options and Vuolti generates the geometry.
Can I sell holders I print?
Not at the moment. The generator is free for private, non-commercial projects. A solution for commercial use is planned but not available yet.
Can I sell or redistribute the STL?
No. Digital model files may not be sold, published or redistributed.
