Parametric CNC Router Dust Shoe #2

Once my CNC router build, fixed gantry CNC router with old industrial supplies (https://openbuilds.com/builds/fixed-gantry-cnc-router-with-old-industrial-supplies.6536/), was far enough along to start using the dust shoe I originally designed (https://www.thingiverse.com/thing:2806963), I realized it was decreasing my usable Z-axis travel. So I completely redesigned it. It's designed to work with a clamp like this one: https://www.walmart.com/ip/Camco-39553-Twist-It-Clamps-for-attaching-RV-Sewer-Hose-Fittings-Pack-of-2/14504314, two round magnets, 1/2" x 1mm thick (although I'm thinking 2-3mm thick would be better), a 64mm diameter trim router (Harbor Freight), a 30mm internal diameter vacuum hose, thin vinyl, and more. But it's all parametric so you can change what you need to. The idea is that the magnets are glued into the magnet recesses. The vinyl I used was a $1 sample from JoAnn's Fabric & Crafts cut to 12" long and 2" wide prior to gluing to the bottom piece and sliding the band around the outside. I've since changed my spindle and downloaded someone else's design instead of tweaking this one. If I were to print this one again, I'd recommend making the magnet holes deeper so that several of the thin magnets I used could be used (or resized for larger magnets) so that it's more difficult for the bottom part to separate from the top. I also didn't have as great of success using the vinyl so I switched to using the bristles removed from a Dollar Tree broom.
