Shapeoko 3 HDZ Dust Boot

thingiverse

My SuckIt dust boot broke several weeks ago. I decided to design and build my own replacement instead of replacing it immediately. I needed to modify it to work better with my SO3 equipped with a Beaver HDZ Zaxis and a powerful 2.2kw water-cooled spindle. This was the outcome. The stock SuckIt arms are still used, as they function well and I'm too lazy to replace them. Additionally, the SuckIt magnet spacers must be reused. The bristles used in this design are inexpensive Amazon 2" bristles (available at https://www.amazon.com/gp/product/B01566L3HQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1). The length of the bristles can be customized by cutting them to any desired size. I opted for longer bristles to prevent the boot from frequently crashing into my clamps. It is printed in three parts: base, hood, and faceplate. These components are assembled using M3 or M4 screws (or equivalents) that were readily available. The faceplate features an ER20 nut hole. This design allows for easy printing without support material required. For those who prefer to use a CNC machine to cut the faceplate, I have included the DXF file. A 2.5" OD vacuum hose is used in this boot design. UPDATE 1: A bottom plate was added to focus more of the suction force forward, towards the cutting area instead of downward. This modification aims to improve dust collection when the hose portion of the boot is detached from the cutting piece and the brushes no longer create a seal. The screw holes on the new bottom plate match those on the top hood, requiring only slightly longer screws for assembly.
