Openbuilds Custom CNC Dust Shoe

This a dust shoe that I designed for my custom made CNC router which is based on the Openbuilds aluminium system.
My CNC Spindle is a 500W 52mm router.
The Dust Shoe consists of 2 parts the upper part and the lower part.
I have attached magnets between the 2 plates (4 in each plate glued on the designed holes ) in order to be easily removable.
The upper section fits very nicely on my router and I use a small screw to further tighten it.
My shop vac has a perimeter of 48mm.
It is still work
