CR-10 Vent Ring 2 shorter

The original vent ring by Filboyt is a great design. I printed all of the other "short" versions but just could NOT get them to clear the print surface sufficiently. Maybe it's just my printer, but it seemed easier to remix the file design minus 1 mm than to try and get all of my mechanical parts to play nicely.

I dropped the vent-ring-short-2 into Tinkercad and shortened the vertical chamber by 1 mm. Now it 'just barely' clears the bed and printed layer for my stock CR-10. .
