Antivibration Frame Kobra 3 v2/v1 Hex bolt version (no drilling)

Remix of the original model featuring bigger holes that allow for use with hex bolts

(original description with some changes)

This project adds a rear bracing system to the Anycubic Kobra 3 V2 without drilling or modifying the printer.

Two diagonal threaded rods stiffen the frame, reducing vibrations during high-speed printing and improving surface quality.

Required materials

2 threaded rods M10 × 500 mm

8 × M10 nuts

8 × M10 washers (wide type recommended to spread the load)

8 × M5 screws (10–15 mm long) for mounting the brackets to the 2020 aluminum profiles

Recommended filament: PETG or ABS (PLA works, but it’s more brittle and heat-sensitive)

Infill: 60% (I recommend 100% if you print it with pla) (grid or gyroid)

Perimeters: 5–6 walls
