LowRider2 CNC - Hose Attachments - Vac-Shoe Adapter for Vacmaster 2.5" Hose

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5010357.

This allows connecting a 2.5" hose from a Vacmaster Pro shop vac to the LowRider 2.

Includes both a Dewalt version and Makita version of the "VacShoeTop." (The original default "VacShoeTop.STL" should not be used, as the redesigned ones offered here allow more airflow. See notes on airflow below.)

My Vacmaster Pro shop vac came stock with a 7' hose. I bought a second matching 7' hose at the home improvement store. I used the coupler I designed (included in this setup) to connect the two hoses. The stock hose ends with a long plastic sleeve. The second hose (bought as an accessory) has a matching long plastic sleeve on one end, and a short plastic sleeve on the other end. Match the two long sleeves into the coupler. The short sleeve on the end then goes into the adapter I designed (included in this setup) on the LowRider 2's router plate.

Notes on airflow for this Vac Shoe Assembly for Vacmaster 2.5" Hose:

• Unobstructed circular opening for the hose (ID) has an area of 3,017 mm²

For comparison:

• Opening in the router plate (Makita version) has an area of 4,035 mm²
• Opening in the router plate, less the round area directly under Makita, has an area of 2,959 mm²

Of importance is approximate size of the "mouth" at bottom of this "vac shoe" set-up. That's not as easy to calculate, so I did not. Instead, this is a poor approximation that I calculated that by adding together the horizontal footprint (1500 mm²) and the vertical "face on" footprint (800 mm²), which comes to 2,300 mm².

I drew inspiration from this item:

'Low Rider V2 - 4" dust collector adapter' - https://www.thingiverse.com/thing:4300201

...and I remixed from these two items:

'Lowrider2 Makita RT0700C Plate and Vacuum Shoe' - https://www.thingiverse.com/thing:3257573

...and the original LowRider 2's "VacShoeTop.STL."

Note: My stock hose fits perfectly in the coupler, but the second hose is a bit loose. I wrapped a rubber band around it, and pushed the coupler over the rubber band, getting part of it in between the hose end and the coupler. This provided a tight fit.

PS: I remade my pen holder design to fit with this new hose adapter. It is available at the link below:
