Bosch PBD 40 - suction adapter v2

This version is significantly improved - position is set independently on the column, size (and filament) was reduced, nozzle is independent part (sometimes can be destroy by drill bit)

Additional parts:

threaded rod M8 - 85-88mm
DIN912 M4x16 
thread insert M4 (outer diameter 6mm)
2x wood screew 3x16
flexible pipe D40mm 75mm 
glue

In case the slider is too loose in the midle part I recommend add on slider transparent tape (standard tape for packaging)
