Cyclone filter for workshop/cnc vacuum cleaner

Simple filter cyclone to do with a CNC milling machine.
You will need:
- 12mm thick plywood sheet (600x460mm)
- 1mm thick sheet of PET (1000x500mm)
- 50mm diameter sewer pipe with the cup with a length of 500mm
- 6 screws M5X45 with nuts and washers
- CNC mill, hotglue gun and dermel

I built this filter to my CNC machine, dust was collected in an industrial vacuum cleaner which unfortunately fairly quickly filled.
The filter is attached to a steel barrel with a capacity of 60l (needed the extra cover - is not in the files).
Now the dust and debris getting into the barrel and the vacuum cleaner is clean.
