Oldham coupling with two custom shaft bores STL: Create a Custom-Size 3D Model

Connect two slowly hand-driven model shafts with a small parallel offset. Raised keys on two hubs engage perpendicular grooves on opposite faces of a center disc. Set the outside diameter and both actual bore sizes; defaults are 36 / 5.2 / 8.2 mm. Grooves have 0.25 mm clearance on each side. Supply bearings that keep the shafts parallel and retain all three parts axially. Each hub has a 3.4 mm radial hole and a top-loading pocket for your own M3 nut; gently tighten suitable screws against the shafts.

With the Oldham coupling with two custom shaft bores template, you can turn those measurements into a custom-size STL. Review controls such as outside diameter, hub a bore, hub b bore, 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.

Start with my measurements

Measurements for your oldham coupling with two custom shaft bores 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.

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

1. Open the oldham coupling with two custom shaft bores product page and compare the model preview with your application.
2. Enter the relevant measurements. Use the units displayed beside each input; convert inch measurements before using a millimetre field.
3. Review the complete geometry and keep a record of your parameter values. Check small openings, mating features and remaining wall thickness.
4. Choose the digital STL purchase option and review the current price and order details before payment.
5. 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 outside diameter, hub a bore, hub b bore, 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 oldham coupling with two custom shaft bores 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.
