A 50mm (~1.97 in) radius insert for the Corner Radius Jig by Warlog. This is the largest possible radius for that jig without making the full arc non-continuous.
Included some extra files for easier remixing than the original model.
The settings for the thread that worked for me were:
Insert printed in red PETG from SunLu, with weird artefacts from ironing. Base piece printed in some old no-name copper PLA.
The author remixed this model.
The insert was modeled from scratch based off of the original's dimensions, so not a strict remix.
