I love this add-on, however in blender 4.3 I am unable to use it, I don't find the mesh under Add list, it is installed and enabled, maybe and most likely I am doing something wrong
The recent blender update breaks this addon, The bolts are non-manifold and also they are super tiny when you first add them. Other than that its good, the bolts are customizable and everything 👍
