Parallel drawing ruler with two connecting arms STL: Create a Custom-Size 3D Model
Create a custom-size parallel drawing ruler with two connecting arms STL for your own 3D printer. Check the model controls, measure the fit and buy the generated digital file.
Transfer parallel lines while drawing by holding one ruler and moving the other, then alternating. Two equal connecting arms keep the edges parallel. The set includes four flat printed parts with 3.3 mm bores; add four M3 bolts, thin washers and suitably secured nuts. Pivot spacing along each ruler equals ruler length minus 30 mm. Joints must move freely without noticeable play. Check edges and parallelism against a reliable reference after assembly. No scale or navigation approval; for light drawing work on paper only. Adjustable dimensions: Ruler length: 120–190 mm; Link pivot spacing: 35–75 mm; Ruler width: 14–24 mm.
With the Parallel drawing ruler with two connecting arms template, you can turn those measurements into a custom-size STL. Review controls such as ruler length, link pivot spacing, ruler width, 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 parallel drawing ruler with two connecting arms 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 |
|---|---|
| Ruler length | Check both endpoints of the named feature, including its working reach or engagement. |
| Link pivot spacing | Use a consistent reference point on adjacent repeated features. |
| Ruler width | Measure across the named feature and allow space for the neighbouring parts. |
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 parallel drawing ruler with two connecting arms 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 ruler length, link pivot spacing, ruler width, 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 parallel drawing ruler with two connecting arms 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.
