No 3D file? Start with a photo, sketch or idea

What a photo tells a printer—and what it leaves out

A photograph shows the appearance of an object from one viewpoint. A printable model describes its shape in three dimensions. The back, underside, wall thickness and hidden connections may not be visible in a picture. Those details need measurements, additional references or design decisions.

For example, a front view of a nameplate can explain the lettering, but the printer still needs its width, thickness and mounting method. If you want a decorative object inspired by a reference, say which features matter. If it must fit an existing assembly, explain that requirement before asking for a price.

Prepare a reference set that answers questions

Use clear, well-lit images that show the whole object. A neutral background makes edges easier to identify. If you have the object, include front, side, back and top views when they add useful information. Label your important measurements rather than asking the partner to infer scale from the photograph.

A sketch can be more useful than a polished picture when it clearly states dimensions and purpose. You can draw by hand, mark the dimensions and photograph the page. Include close-ups of any attachment, recess or feature that must be reproduced.

• State dimensions and units in the written request.
• Explain which parts of the reference to keep or change.
• Describe the expected use and whether exact fit matters.
• Include colour, quantity, location and timing.
• Share only images and designs you are entitled to use.

Separate model creation from printing

Model creation, design revisions and physical printing are different tasks. Ask whether the partner can create the model, what information they need and whether their quote includes that work. Not every print partner offers design services, so a reference-only request may need further discussion.

Agree how you will review the design before production. For a simple nameplate, a preview and dimensions may be sufficient for your decision. A fitted part may need a prototype and another revision. Confirm how many changes are included, what additional revisions cost, and whether a usable model file is part of the deliverable. Do not assume those terms are the same for every partner.

A reference link or existing model can help

If you find a similar design in a model library, share the original page link. It can clarify the shape and show whether a downloadable file exists. Read the creator’s licence and any conditions for using a printing service. Download availability alone does not establish permission for every use.

Mini Objects’ Ideas page lists model libraries and design tools. A generated or downloaded model still needs a printability review. Ask the partner to check its dimensions and geometry rather than treating a visually convincing preview as proof it will print correctly.

Turn the references into a Mini Objects request

Choose the starting point that matches what you have: a model, reference link or idea with an image. For the image/idea route, include a reference upload and a written description. Add quantity, dimensions, preferred material if known, and your six-digit PIN code.

A useful example brief is: ‘A desk nameplate reading ANIKA, 150 mm wide, with a stable freestanding base. White lettering on a dark base, one piece for indoor display. Please quote model preparation and printing, and show the proposed size before production.’ These details give a partner something concrete to evaluate without requiring you to learn modelling software first.
