Body Tools for Bonelab is a free mod designed for Windows that enhances the gameplay experience by providing a variety of tools to modify your avatar's appearance and physics. This mod is fusion-friendly, meaning no code modifications are necessary for installation. Key features include the Head Offset Toggler, which corrects the avatar's head position for better third-person visibility, and the Head Mesh Revealer, allowing toggling of head and hair mesh for spectator views.

Additional tools include Physical Legs, which add physics to your avatar's legs, and the Rig Unleasher, granting players more freedom by removing the rig leash that typically confines movement. Other features like the Holster Hider and Rig Stripper allow for further customization by hiding various avatar elements. However, users should be aware that the functionality of these tools may vary with updates to Bonelab.
