This is a carriage rail brush I designed for a Lead 1010. Mostly for the Y carriages. This keeps debris off the path of the wheels so that the wheels don't get embedded with crud. it should just snap in, printed with PETG, and optional window (need a piece of plexi to keep stuff from going in). Also have a solid version without window.
Will need 7900T707 from mcmaster for the brush material, can be found here -> McMaster-Carr
open to feedbacks and suggestions. I have a couple other improvements in mind for the Lead, those will come soon...
