Anet A8 Heatbed corner for 210x200mm glass

For my Anet A8 I have bought a 210x200mm glass. I have fixed it with tongs but they hinder the extruder. So this heated corners block the glass without anything else and also fix the springs under the heated.

- Heatbed_corner_FR-BL: Front Right corner and Back Left corner

Hope you will love it!

EDIT : I have added the fusion 360 file if you want to remix !
