Here we offer part of our expansion series for a 40W CO2 laser for the new model. 
 
 By exchanging with this suction device , you have the option of enlarging the laser's travel path without sawing the original suction device. 
 The suction is printed from PLA + material with a very stable infill. 
 
 
 This suction only fits into the new model of the 40W K40 laser.
