I had a(n unofficial and unsupported) concept that I didn’t get a chance to test thoroughly, but it’s meant to be used similar to how my original design was - Thumbscrew on the sides to secure height (M5, not M4!), Rockler hose in the front angled out, and usable with a flexible strip brush from McMaster. You’re welcome to give it a shot.
Note: The two “nostrils” on top are meant to bleed a little airflow through the base section to help cool the spindle. It’s probably overkill, but wrapping the section of the spindle that already runs 5-10F warmer than the original in a low-conductivity plastic shroud bothered my engineer-brain. (We used larger bearings for greater rigidity compared to the rectangular version of the spindle.)
