FDM design guidelines for quote-ready parts.

Use this page to prepare files, photos, measurements, and part requirements before requesting a production quote. The goal is simple: fewer unknowns, faster review, and better production planning.

Accepted file typesPrintability checksMaterial planningProduction expectations
Accepted review files

Start with the cleanest file available.

Production-ready 3D files are best. Photos, drawings, and measurements can help with first review when a model is not ready yet.

Best for quoting

STL, STEP, STP, 3MF, and OBJ files. STEP/STP files are especially helpful when geometry accuracy, mounting points, or mechanical fit matter.

Helpful support files

PDF drawings, photos, sketches, TXT notes, CSV part lists, and ZIP packages can be attached when they support the quote request.

File organization

Use one file per part when possible. Name files clearly with part name, revision, material preference, and quantity if known.

Scale and units

Confirm whether the model is inches or millimeters. If critical dimensions matter, include a drawing or note with those measurements.

Printability review

What we look at before production.

FDM parts are built layer by layer, so the model, orientation, material, and use environment all affect the finished result.

Wall strength

Thin walls, small tabs, narrow clips, and tiny posts may need design changes depending on load, material, and print orientation.

Overhangs and supports

Steep overhangs, cavities, and complex underside features may require support material or a different orientation, which can affect finish and price.

Fit and tolerance

Press fits, holes, hinges, snap features, and mating parts should include tolerance expectations and whether test samples are needed first.

Heat and sunlight

Parts used outdoors, inside vehicles, near motors, or in warm environments should include temperature and UV exposure details.

Surface expectations

FDM parts have layer lines. Tell us which faces are visible, which side should look best, and whether cosmetic finish matters.

Quantity and repeatability

Prototype, small-batch, and repeat production jobs are reviewed differently. Include first-run quantity and expected reorder volume.

Replacement part review

Photos can help when a model does not exist yet.

If the project starts with a broken plastic part, send clear photos from multiple angles, measurements, the product it came from, what broke, and how the part is used. We will review whether a model is needed before the part can be manufactured.

Send these when possible Overall length, width, height, and wall thickness Hole spacing, peg diameter, and clip geometry Photos with a ruler or caliper for scale How the part failed and where it carries load
Protected intake

Upload files only through the completed quote form.

The quote form is built so project files are submitted with customer details, project requirements, and design-rights confirmation instead of a random public file drop.

Required project detailsName, email, phone, project type, material goal, quantity, target date, delivery preference, and use-case notes are required before the request can be sent.
File limitsAllowed files include model files, drawings, photos, PDFs, TXT, CSV, and ZIP packages. The current quote form allows up to 5 files and 15 MB total.
Rights confirmationSubmitters must confirm that they own, created, licensed, or are authorized to submit the design files and related materials.
