Summary
This design is made for the popular K40 Laser Cutter.
It supports a standard 100mm exhaust pipe.
3mm Plywood
3mm Felt (Polyester)
Tape
Wood Glue
Exhaust Pipe D=100mm
The pictures show the assembly step by step. Please note the position of the tape on the top part. Leaving a margin of at least 2mm to the side edge for glue side and top part together.
I use a 3mm Polyfelt for sealing between K40 housing and the exhause. You can use the wood glue to fix it on the plywood.
Happy cutting...
