In its basic configuration the Blacknose Laser cutter comes with a water pump and a 35L tub to put water in. I find myself moving my laser around quite a lot (especially while it is in the kitchen/utility room) and it is a pain to move a full tub and the work stand so I laser cut myself a frame to hold the tub onto the work stand. This frame is made from 12mm poplar and requires no glue to keep it together. The two horizontal pieces hook round the vertical legs and stop the frame from sliding off, it also spaces out the vertical slats. The slats have a slight dent in them which stops the tub slipping off the sides of the work stand.
