💡 What is a shaft support block used for in motion builds? Shaft support blocks keep round linear rods locked in place so carriages slide without wobble or binding. - Handy in CNC tables where repeated passes need repeatable accuracy - Common upgrade in printer frames to cut vibration during high speed moves - Works with standard 16mm rods in both hobby and light industrial setups
