This 3D printed slop stop is for use with the festool front rail support.
As you may know the location pin on the front rail support is slightly smaller than the T slot in the festool rails causing play (slop) in the rail when located.
This 3D printed insert removes that play by creating a tight fit for the location pin of the rail support.
Simply slide into position and tighten the provided M4 grub screws.
The insert position can be moved to ensure you always get the tightest fit for maximum accuracy.
