Specification Brand : 3Dman BulletPoint1 : 【Upgrade】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. BulletPoint2 : 【Application】Replace original spring leveling for Creality 3D Printer Hot Bed/ Platform. The 1/4 quantity in the package is a short column. BulletPoint3 : 【Function】Larger contact surface than spring, reduce shock, heatbed silicone leveling column better to level your 3D printer. BulletPoint4 : 【Size】Height: 12 pcs 18mm(0.71inch) + 4 pcs 16mm(0.63inch). There is a Bed Cable cage at the left rear of the Creality Ender 3D Printer series, the short column will fit there. And other 3D printer series take 4 high columns. BulletPoint5 : 【Package】16 PCS heatbed silicone leveling column.
