Remixed from here.
Rethreaded (just finger tighten and snug with wrench)
Slightly thicker walls
Top collar adds aesthetic and creates a depth stop to help prevent overtightening
Original summary from @Dash:
Low mass. Close to the mass-center of the print-head. No screws. All you need is a super-glue
Added a picture of side by side comparison. The one on the right is my remix.
