Spur differential with two hand-operated outputs STL: Create a Custom-Size 3D Model
Create a custom-size spur differential with two hand-operated outputs STL for your own 3D printer. Check the model controls, measure the fit and buy the generated digital file.
This spur differential connects a rotating carrier to two coaxial outputs. Two axially offset planet gears accommodate different output speeds; with the carrier held still, the outputs turn in opposite directions. Intended for slow hand-operated mechanisms and custom demonstration models. The set comprises a carrier, cover plate, two output gears and two planet gears. Add two smooth 3 mm planet axles, three M3 fastener sets with nuts, suitable washers and your own two shafts. The hubs have blind bores; do not push the shafts against the bore bottoms. Radial 3.3 mm pilot holes can be tapped M4 for clamping screws.
With the Spur differential with two hand-operated outputs template, you can turn those measurements into a custom-size STL. Review controls such as gear module, teeth on each output gear, width of one meshing level, check your model in the preview and choose the digital file. You buy the generated STL and print it on your own 3D printer, using your preferred filament and slicer settings.
Measurements for your spur differential with two hand-operated outputs STL
The product page exposes the following useful geometry controls. Work from your measured parts and check the displayed units and the preview before entering final values.
| Model control | What to check |
|---|---|
| Gear module | Check this feature against the matching component and confirm its effect in the 3D preview. |
| Teeth on each output gear | Check this feature against the matching component and confirm its effect in the 3D preview. |
| Width of one meshing level | Measure across the named feature and allow space for the neighbouring parts. |
| Your output-shaft diameter | Measure across the circular feature and confirm which mating surface it represents. |
| Tooth backlash | Check this feature against the matching component and confirm its effect in the 3D preview. |
Confirm the working geometry before buying the file
Compare the pictured shape with the actual task, not only the product name. Mark which faces touch other objects, which parts need to move and which pieces are supplied separately. The model controls change an existing design; they do not automatically add a feature that the template does not include. Check the complete motion or assembly space in the preview before choosing your final dimensions.
Configure the model, buy the STL and print locally
- Open the spur differential with two hand-operated outputs product page and compare the model preview with your application.
- Enter the relevant measurements. Use the units displayed beside each input; convert inch measurements before using a millimetre field.
- Review the complete geometry and keep a record of your parameter values. Check small openings, mating features and remaining wall thickness.
- Choose the digital STL purchase option and review the current price and order details before payment.
- After receiving the STL, open it in your slicer, confirm the imported dimensions and inspect the layer preview before printing.

Check a first print before making more
A CAD dimension and a printed dimension can differ. Print a fit sample or one prototype before making a batch, and check the features that contact other parts. Choose print orientation, supports and material for the actual geometry and application. There is no universal clearance or print profile that guarantees the fit on every machine.
Before you choose your STL
Why configure the model instead of scaling a download?
Uniform scaling changes all dimensions together. Here you can work with the available controls, including gear module, teeth on each output gear, width of one meshing level, and check the result before purchase. Keep your input values for later revisions: the downloaded STL contains the final mesh, rather than the original parametric editing history.
What do I buy?
Select the digital STL option for the file you will print yourself. Review the current price and selected configuration before paying. Ordering a finished print is a separate option.
Make the next print fit your project
Have your measurements ready? Open the spur differential with two hand-operated outputs template, adjust the model and inspect the preview. When the geometry matches what you need, choose your STL and take it to your own printer.
