Anycubic kossel spring leveling system and bed holder

I created myself a bed leveling system from scratch. Print everything 3 times. Besides that you will need:

3x springs with 18 mm diameter
9x M4x20mm screws
18x M4x12 mm screws
27x M4 nuts
3x M4x16mm screws
3x M4 T-Nuts

UPDATE:

I updated my bed holder by now. It has a lower profile now and a more secure base which is connected to printer. I think you only need 3 more M4 nuts and M4x12 mm screws additonally.
