There are a number of different designs for dust shoes. It's surprising how little is needed for effective dust collection --- some of the designs are simply a folded piece of transparency film (or a cut-off from a soda bottle), a threaded part to hold it in place, a vacuum wand or extension zip-tied to the universal spindle mount and possibly a pierced retaining piece to hold the film to the end of the vacuum.
Far more elaborate is Improbable Construct's Dewalt DW660 Dust Shoe which has removable skirt pieces allowing for it to be adapted to various length end mills. One example of it in use is in the forum discussion: Cutting foam for dust Shoe.

- Re: $5 SO3 Dust Shoe
- Media:Shapeoko3_Spindle_Mount_Dustshoe.svg --- universal design for the SO3 spindle mount which may be used for other spindle mounts and will accommodate either a DWP611 (untested --- spindle mount holes and other spacings may need to be adjusted) and a Makita RT0701. Requires 4 coupler nuts, 8 matching screws of suitable lengths (#10-24 works well and is easily and affordably sourced), 4 magnets (suggest using at least two which may be fastened in place using screws), 2 or 4 small screws and matching nuts (M3 works well), washers to use as spacers
Craft foam, transparent plastic and bristles are the typical choices.
