I’m constantly adding new features to my Tevo Tarantula printer. The latest addition is a bed leveling sensor.

It improves the quality of the prints a lot and in addition you don’t have to adjust the print bed manually every time. If properly configured it runs a measurement sequence of several points (3×3 in my case) before every print and uses this information to compensate during the print.

Where to buy?

You can find it in many places. I bought it here (Banggood)
