3D modeling when you do not have a printable file

A printable model from a sketch, photograph and dimensions

Modeling is useful for a replacement plastic part, a new bracket or housing, or a change to an existing shape. We focus on models intended for FDM printing. A photo shows appearance; measurements establish size, hole positions and interfaces.

What to include in a modeling request

1. Photos or a sketch from several sides, including the place where the part will fit.
2. Overall width, length and height, units, and critical hole, mounting and mating dimensions.
3. The purpose of the part: loads, movement, temperature, moisture and sunlight exposure.
4. Required quantity and preferred date. For a repeat job, include the previous order number.

Agree the model before printing

We review the task and quote modeling separately. The scope, deliverable files, permitted use, revisions and timing are agreed before work starts. A print quote alone does not promise a parametric CAD source file.

Start with a test part

For a new design, print one sample to check fit and function before a full batch. Model changes and reprints are agreed separately. Printing usually takes 2–5 days after approval and payment; modeling and transit require additional time.

The modeling and printing quotes specify separate scopes and costs. Confirm the measurements, material and delivery requirements before accepting the work.
