Starrett 25-281 Dial Indicator Holder V2 for Ender 3

thingiverse

I designed this mount for the Starrett 25-281 dial indicator for my Ender 3. It integrates a direct replacement back plate so it fits perfectly and has zero movement in the holder which allows for precise leveling of my print bed. To use, I start with a 0.1mm feeler gauge between my print nozzle and the front left bed corner. I then use the dial indicator to manually tram my other bed corners to that initial reference corner height to ensure I get a perfectly level bed every time. No more using paper.
