Laminar flow improves blowing.
It is recommended to print with ABS, I made with white PC/ABS compound.
No supports needed.
Used 0.2 mm layer height vith variable height at holes (~0.12).
With infill combination it takes about 16-18 minutes to print.
The holes should be drilled after print with a 1-1.5 millimeter drill bit, the main hole in the center should be drilled 2 millimeters.
On my Acmer 20W machine I got an improvement in cutting:
3 millimeter plywood, 25 l/min airflow:
before - 6mm/sec
after - 8mm/sec.
Attached STEP file so you can adjust sizes for your laser engraver if needed.
