Radius Templates and Gauges: 3D Models and STL Files

This collection gathers STL files for radius templates, gauges, corner jigs and assortment box layouts. It helps when you need to mark, check or cut a curve and want a printable guide rather than a one-off drawing. Files vary in scale and part count, so the author's page is the place to confirm details. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Radius Templates and Gauges: 3D Models and STL Files»

Radius gauges come as single tools or sets with inner and outer arcs for checking curves. Corner radius templates and router jigs guide a cutter around a rounded edge, often with several radius options on one body. Assortment box packs use layout variants to organize small parts, and their differences lie in compartment count and wall thickness.

When choosing a file, check the listed radius range, the number of separate parts, and whether assembly is required. Look at the author's print photos to judge surface finish and how the gauge sits in the hand. For printing, confirm the material and settings the author lists, and note whether supports are needed for overhangs or engraved labels.

To narrow the results, try synonyms such as fillet gauge, corner radius jig, router template, and curve template. Related searches include radius set, layout box, and measuring tool. Adding a size or unit to the query, such as metric or millimeter, can separate gauges from decorative models.

FAQ

Frequently asked questions

What is a radius template used for?
It helps mark, check or cut a rounded corner or curve. Gauges compare an existing edge to a known arc, while router jigs guide a tool along the shape.
How do I choose the right radius size?
Start from the curve you need to match or create, then check the range listed on the model page. If the file is a set, confirm which sizes are included and how they are labeled.
Do these models need supports?
That depends on the shape and orientation. Check the author's notes and the slicer preview before printing.
How can I find related radius tools?
Try terms like fillet gauge, corner jig, router template or curve template. You can also search by unit, such as metric, to narrow the results.
