Spring Delta/kossel bed support for 2020 bar

Spring support that fits on a 2020 bar with a aluminum heatbed + glass plate (total height 6mm **).
Printed with PETG or ABS for having no problem with the heatbed temperature.
I use 3 of these on a Delta/Kossel plus from Anycubic with a 240 mm heatbed + 240 mm glass plate(it can be used also with a different model/size printer).

**the updated version can be used also with a 3mm tall bed (only glass or only heatbed).

You need these material :
-1 M3 screw and 1 M3 nut for fixing the plat
