Although the Stepcraft CNC Routers have decent protection of the gantry rail by the rubber flaps, I had the issue of chips entering.
These chip guards cover the part were the rubber separates when the gantry moves.
Print the part straight up and use a 3 to 5 mm brim to add some extra stability during printing. and no supports are required.
The guards can be easily fixed with some double sided tape.
