Bosch GTS XC10 parallel guide extension

I purchased this 3mm 1,40m long aluminum profile: (You can use any other, but make sure that it is 60x25x3, otherwise this modelfiles won't fit.)

Drill two holes at same location than existing on parallel guide. Use the 3D printed part “paralellanschlag schraubensicherung” pleace an M8 nut inside an push into the profile. If you printed correct the part is a tight fit inside profile. So no need for clue to hold nut position.

You can use this knob for your screw head:

Endcaps are just for optics and to prevent contact with aluiminum edges at front an back of the profile
