Prepare a Miniature STL, 3MF or OBJ for Printing

A printable miniature file needs to communicate the object you want, at the size you want, with the permission to produce it. You do not need to solve every manufacturing question yourself. You do need to identify the model, specify its intended size and explain any important details that a printer should assess.

Keep three things together: an untouched source file, the version you intend to upload and a short written brief. If you change the model later, give the new version a clear name so an older file cannot be mistaken for the approved one. A screenshot can help explain your intent, but it does not replace the geometry.

A brief you can copy

  • Model: file name and creator or source.
  • Authorization: the terms or permission covering this print.
  • Finished dimensions: height, width or base size in millimetres, with the measurement reference.
  • Quantity and purpose: how many objects and whether they are personal pieces or another use that needs review.
  • Important surfaces: the face or other areas where appearance matters most.
  • Questions: fragile details, separate pieces, finishing or required timing.

What if I only have an image?

An image or character-editor link is useful reference material but may not contain a printable model. Check whether the creator provides an authorized printable export. If the object still needs to be modelled, use a custom request rather than presenting it as printing alone.

What if I do not know the right scale?

Measure an existing figure you want to match and identify how its height was measured. Include the base and maximum outside dimensions. Do not rely only on a familiar scale label.

Does uploading approve every detail?

No. Review the displayed dimensions and options, and flag any feature you are uncertain about. A file that can be opened is not necessarily suitable for the finish, strength or use you have in mind. Start with the checks below, then upload your authorized file.

Prepare a miniature file before uploading

Start with a copy of your original file so preparation does not overwrite it. Check the model’s dimensions in a viewer or modelling application, then write down the intended finished height and base size in millimetres. A unit mismatch can produce a plausible-looking preview at the wrong physical size.

  1. Inspect the contents: identify the figure, base and any separate pieces. Remove unrelated objects from the export you intend to print.
  2. Review delicate features: look for thin equipment, disconnected parts and unsupported-looking details. Note concerns instead of assuming they will print unchanged.
  3. Confirm the export: use a supported printable format and retain the source file.
  4. Check the upload preview: compare its dimensions with your written measurements before accepting the quote.

Orientation and supports can affect a model’s surface. Tell the printer which visible areas matter most, but do not assume a universal orientation or minimum thickness works for every miniature.

Upload the authorized file with your desired size and relevant notes. If the model needs design changes rather than printing alone, explain that before treating the estimate as the whole project.
