Major Upgrade From The Original Leveling Spring - Now you spend much less time leveling your 3D Printer bed. Once you get level, you won't need to re-adjust for quite a while. Effectively avoid layer shifts caused by bed shaking during printing. The trick is that the short mount needs to go ON TOP of the strain relief, not under it.

The 1/4 quantity in the package is a short column(3 short in 12 pack; 2 short in 8 pack). There is a Bed Cable cage at the left rear of the Creality Ender 3D Printer series.short column will fit there, and other 3D printer series take 4 high columns.
