I prepared 5 models, one for each size (2, 3, 4, 5 and 6mm). Attachment is mounted on threaded end, like most of dremel's accesories.
Works with my oldie-but-goldie dremel 300. I hope that it will work with newer models too.
Note: Sanding 6mm chamfter on plywood is really time-consuming. For bigger chamfters on harder materials I recomend using edge router.
The author marked this model as their own original creation.
