Imdinnogo BCZAMD Heatbed Silicone Leveling Column, 3D Printer Hot Bed Mounts Column Stable Tool Heat-Resistant Silicone Buffer for Prusa i3 Plus A8 Wanhao D9 Mega, 4 Pack Brown

These are great as they stay where you set them. On a CR-10S, you need to use an adjustable z-axis endstop bracket or youll have to use shims as these are thicker than the stock springs.

Ill never have to level my bed again!

Great replacement for bed springs. Feels durable.

Works way better than springs.
