JessEm Compatible Ring Inserts for Router Lifts - Downdraft Dust Collection Version

Printed with 0.6mm nozzle using Prusa .20 STRUCTURAL profile using Spectrum PLA Pro and the Prusament PLA profile in PrusaSlicer. No supports needed. 

These really enhance the dust collection in the downdraft box that I use [Rockler Dust Bucket] (the last two photos are the leftover dust that didn't make it after template routing 75 linear feet of dense colored MDF)

Changed numbers to be the actual size of the hole in inches. Added slots. Made bottom solid. Kept the “screw” geometry on the sides as well as the wrench holes.
