Example result
A shelf bracket with countersunk screw holes
The bracket from two sides
Seen from above
Size: 24 × 60 × 60 mm, one part. Files:
- model.stl and model.3mf;
- model.obj, model.glb and outline.dxf;
- model.js, with the legs, the hole positions and the screw sizes at the top;
- a README.
The README suggests printing it on its side so the layers run along the legs, in PETG with 40% infill and 4 walls. It is a bracket for light shelves, and its strength depends on the plastic and the printing.
Client: someone who needed one more bracket like the ones under their kitchen shelf, to the same size. Task: an L-shaped bracket with 60 mm legs, 24 mm wide and 5 mm thick, with a rib in the corner and two holes per leg for 4 mm wood screws, countersunk so the heads sit flush.
The client and all details are made up.
About this service
A 3D model of a clamp or holder that fixes a pipe, a tube, a rod or a hose to a wall, a desk edge, a frame or another tube. It can be a clip that snaps onto the tube, a saddle with screw holes, a holder for several tubes side by side, a spacer between two tubes or, in Premium, a clamp of two halves joined by screws. You give each tube's outer diameter, the distance from the wall, the spacing and the screws, in mm. You get a ZIP archive: STL and 3MF to print, OBJ, GLB, a DXF outline, the code with the sizes at the top, a README with printing advice and pictures from four sides. From Standard the file holds 2 or 3 versions of the diameter. Strength depends on the material, and plastic softens with heat. Not for gas, pressurised, hot or exhaust pipes. We do not print or ship parts.
What is included
- What you getA ZIP archive with model.stl and model.3mf for 3D printing, model.obj for 3D editors, model.glb for viewing on the web and in augmented reality, outline.dxf with the outline seen from above for CAD and laser cutting, model.js with the main sizes as named numbers at the top, a README with printing advice and 4 PNG pictures of the 3D model from four sides, also shown on the order page. The two halves of a clamp lie side by side, ready to print separately.
- Clips and saddlesSnap onto a tube or screw down over it
- Several tubesOne holder for tubes side by side, at the spacing you give
- Diameter variantsFrom Standard, 2 or 3 versions of the inner size to find a firm grip
- Two-part clampIn Premium, two halves with screw holes
- Printing adviceWhich side down, supports, layer height, infill and material, in the README
How it works
- 1MeasurementsYou measure the tube's outer diameter, ideally with a caliper
- 23D modelWe build the 3D model and check that it is a closed solid of the sizes you asked for
- 3Try itYou print the diameter variants and try them on the tube
- 4ChangesYou send what to change, with measurements, within your package
What we need from you
What the clamp holds and where: a pipe on a wall, a rod on a desk edge, a hose on a frame. The outer diameter of each tube in mm, measured with a caliper if you can; if it is not round, its width and height. How many tubes, and the distance between their centres. How far the tube should stand from the surface. The screws and where the holes go, or the thickness of the edge the clamp grips. Whether it works outdoors, in sun or near heat. A sketch or photos with a ruler.
We will ask you:
- What does the clamp hold, and where?
- Outer diameter of each tube, in mm
- How does it mount?
- Where does it work?

Payment protection
You pay when you order, but the money is released only for accepted work.
- Fixed priceThe package price does not change after you pay.
- The money is reservedWhen you pay, the amount is only reserved. It is released to the service once you accept the work.
- Checked before deliveryEvery result goes through a quality check before it reaches you, and you see it on the order page before accepting it.
- Free revisionsAsk for changes within your brief as many times as the package allows.
- Acceptance after 3 daysIf within 3 days of delivery you neither accept the work nor ask for changes, it is accepted automatically. If you write in the order chat after delivery, the order waits; once we answer, we may start the 3 days again and will say so in the chat.
- Redo or a full refundIf the result does not match your brief and the revisions did not fix it, or the work takes more than twice its deadline, write in the order chat: we will redo the work or refund the payment in full.
Questions and answers
Which pipes is it not for?
Gas lines, pressurised water or air lines, hot water, heating or exhaust pipes, and any place where a pipe coming loose would be dangerous. It holds and tidies tubes; it does not seal them.
What if it is loose or does not snap on?
Print the diameter variants from the Standard package and keep the one that grips. A clip bends as it goes on, and how well it does depends on the material; the README suggests one. If none fits, say by how much it is off and ask for a change within your package.
Will it last outdoors?
That depends on the material: some plastics soften in the sun or turn brittle in the cold. Tell us where it works, and the README suggests a material. We cannot guarantee its strength or how long it lasts.
Can you edit my STL of a clamp?
No. We build a new 3D model from your sizes, a sketch or photos with measurements. We do not print, sell or ship it either: you print it yourself or at a print shop.
