Creality CR10S bed spring tensioners

thingiverse

These custom blocks measure 7mm high and feature an 8mm diameter recess that adds a bit more tension to the bed springs. The core of each block has a 4mm diameter, designed specifically for the adjustment bolt. This thoughtful design prevents accidental adjustments by simply touching the adjustment wheels. They're particularly useful when using mirror tiles as the new bed, which is thinner than the original glass bed and thus generates less tension in the springs. To further secure the adjustment wheel, consider installing 4mm wing nuts to lock it firmly in place.
