Kossel 240mm bed support with lock screw

This is my version untested of bed support for 2020 profile kossel with 240mm bed I use anycubic kossel plus and sometimes bed moving during the print. I'm not able to find any support to fix the bed to base.

This is not for glass or ultrabase version, its only for aluminium 3mm heat bed.

You just need put a screw 16mm at least and insert a M3 nut a hole (only enter in one way)
