Ender 3 Spring Cap Spacers

You don't need to buy an upgraded spring kit,

These are spring caps designed for the Ender 3 and Ender 3 Pro. They will likely fit other makes and models.

Place one on each end of each spring. Combine these with the long, skinny springs from the Harbor Freight spring assortment for a dual spring set-up and M4 lock washers on the knobs for a very stable build platform.
