Brass knuckle siêu bền – dùng để bẻ nứt hạt (cracking nuts)!

Really solidly made brass knuckle.
It should be printed with 10 walls and 100% infill.
The 3MF file is configured and ready for printing; the STL file requires manual setup according to your preference — it just needs to be separated into individual objects because the STL contains three solids in one file.

Tested.

Screws like the ones shown in the photo were used, probably M5 with a 20 mm thread length and a head designed for an Allen key.

In the photo showing the build plate of the Bambu Lab P1S, the layout optimized for quality and appearance is presented.

The model and design are prepared for FDM printing, with overhang angles up to a maximum of 45 degrees. The only overhangs are in the areas where the screws are located. A glue-together version will be added in the future.

The photos show the printed model made from PET-G Carbon Look filament by Rosa.
