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 replacement part or a bracket to print, from your sizes, a sketch, a drawing or photos with measurements: a broken clip, a knob, a cap, a shelf support, a bracket, a clamp, a spacer, a simple gear or a pulley. Measure the old part or the place it goes, ideally with a caliper, and send the sizes in mm. You get a ZIP archive: STL and 3MF files to print, OBJ for 3D editors, GLB to view it on the web, a DXF outline, the code with the main sizes at the top, a README with printing advice and pictures from four sides. From the Standard package the file holds size variants, so you print them and keep the one that fits. Strength depends on the material and the printing and is not guaranteed. Nothing safety-critical is made: no parts for brakes, steering, child seats, medical devices, climbing or lifting gear. A replacement for your own use is fine; copies sold as a brand's originals are not.
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, which are also shown on the order page. With size variants, each one lies beside the others, ready to print.
- From your measurementsSizes in mm, a sketch, a drawing or photos with a ruler
- Size variants to test the fitFrom the Standard package, 2 or 3 versions of the tight size side by side
- Holes, slots and rounded edgesUp to 25 holes and cut-outs, rounded edges and chamfers from the Standard package
- Simple gears and pulleysFrom the number of teeth and the sizes you send
- Printing adviceWhich side down, supports, layer height, infill and material, in the README
How it works

- 23D modelWe build the 3D model and check that it is a closed solid of the sizes you asked for

What we need from you
What the part is, what it does and what it fits onto. Its sizes in mm, measured with a caliper if you have one: the overall size, the thickness, the diameter and position of every hole, and the sizes of whatever it fits onto, such as a shaft, a rail or a tube. For a gear or a pulley, the number of teeth, the outer diameter and the bore. A sketch with sizes, or photos of the old part or the place it goes with a ruler next to it, from above and from the side. Which size must fit exactly, if you want variants to test it. The build area of your printer if the part is large, and the material, if you know it.
We will ask you:
- What is the part, and what does it do?
- Its sizes in mm
- Which size must fit exactly?
- Where does it work?
- Your printer and material

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
Will it be as strong as the original?
We cannot promise that. Strength depends on the material, the infill and the way the part lies on the printer, and the README gives advice on them. A printed part is often weaker than a moulded or metal one, so it is not for anything safety-critical.
Which parts do you not make?
Parts for brakes, steering, child seats, medical devices, climbing or lifting gear, anything that holds a person, and weapons or weapon parts. We also do not copy branded or patented products or make parts to be sold as originals; a replacement for your own use is fine.
What if it does not fit?
We never guess a size the fit depends on: if one is missing, we ask you. Print a test piece first, or the size variants from the Standard package, and keep the one that fits. If it still does not fit, send the measurements of what is off and ask for a change within your package. The main sizes are also named numbers at the top of model.js.
Can you edit my STL?
No. We cannot open a file you send, such as STL or STEP, and edit it. We build a new 3D model from your sizes, a sketch, a drawing or photos with measurements. We also do not hand over STEP, SolidWorks, Fusion or other CAD source files: you get STL, 3MF, OBJ, GLB, a DXF outline and the code.
Do you print it?
No. We make the 3D model and its files; you print it on your own printer or order printing from a print shop. We do not print, sell or ship anything. The printer, the material and the printing settings are yours, and the README gives advice on them.
