I have a mill and couldn't make these for this price. All sides are machined and perfect finish. I do wish there were some more holes for more mounting options but that's no fault of microswiss. I ended up mounting different extruder then the ng but definitely will consider it for next machine.

Micro Swiss NG™ Direct Drive Extruder adaptation plate for Creality CR-10 / Ender 3 Printers (Linear Rail Edition)

Exactly what i expected from micro swiss. Perfect fit and impecable machining. Made a great improvement over the wheels on my ender3 v2. Would recommend this company and their products to anyone.

I am glad Micro-Swiss came out with linear rail versions of for the Micro-Swiss NG bought one for the Ender 5 Plus and one for the Ender 3 V2. There are a few suggestions for things that I like to see in the near future that are watercooled hotends (so silent and stable temps) copper heat block for the Ender 3 S1 and machined BL / CR-Touch mount for the NG line-up I'd ordered one in a heartbeat.

Fits perfectly,runs smoothly, and nice and well machined
