Anycubic Kossel Heated Bed 220mm holding plates & pads - Laser cut

This is a work in progress!
Laser cut heated bed holding pads and plates for a Anycubic Kossel 3D printer.
The heated bed is 220mm diameter, the glass plate is 200mm diameter.
Main plate: Yellow layer
Ring plate: Blu layer
Holding pads: Magenta layer

Has you can see from photos, with this design you need to lock down the plexi main plate with screws, by doing this you have to cut holes on the heated bed alu circumference. I will do a new design.

M4 screws and nuts.
6x M4 10mm long ->
