Description:

The ender 3 leveling knobs are more substantial than the cheap black plastic ones..
The red color ends some of the fumblings by feel to locate them, the wheels are nice too, the knurling is nice and grippy and it's pretty easy to turn them too.
The springs are a bit longer than the one on the printer, which gave you some more adjustment range for leveling. The increased tension means less slop when adjusting. The longer springs mean you will have to manually adjust your zstop so that your nozzle doesn't crash into your bed and potentially ruin both.
Everything feels tighter and less wobbly. You do not need to re-leveling near as often..
HICTOP bed knobs are suitable for Ender 3/3 Pro/3 V2 Ender 5/5 Plus/Pro CR-10 CR10S/10S Pro CR 20 3D Printers.
