Heatbed Corner for glas 215x215x3

I bought a glas from amazon for my Anet A8 called VS Electronic 840569 Glaspanel für 3D-Drucker, 215 mm x 215 mm x 3 mm , but it was not 220x220, so no corner fittet it perfect. Everybody use those Photoclamps, but I got rid of it by designing my own corner. Sharing it, so you can use it too. The glas snaps in and fits perfectly.
No more clamps, because they get in the way when printing big stuff.
This is my first work and it works fine for me.
