As i have seen many covers and leveling options for the Anycubic Delta Kossel Pulley, i decided to make a combined one.
This is made to use with 200mm glass and NO heat bed.
Insert an M4 nut in the plate and you can use M4 screws in any size you prefer.
The place where the notches are positioned is off the position of the stepper motors.
Even M4x50mm will not hit the motors.
The cups for the springs go into the respective holes on the plate.
You can use some ballpoint springs to give counter pressure to the glass plate.
Just don't use springs that are stiff.
Keep in mind, by using this you will reduce the printing height with about 10mm and you need to adjust your homing setting in your firmware (Marlin on the Anycubic)
I printed them all on 0.1 and 100% infill as i wanted to have it all as sturdy as possible due the pressure that the springs put on the glass plate.
If you want to go lower, all up to you.
Only use some support on the cups and the notches, it is possible to use some where the nuts need to go in on the plate but it will be a pain in the ... to remove them and clean it out.
Not each glass plate is of the same dimension.
In case your glass plate is a tad smaller, you can use a piece of foam, for example what you use on the door to keep the wind outside and stick it on the small edge in the notch where the glass will touch.
You need to position the plate on the flat surface with the M4 mounting brackets upwards,
These cover plates are no longer on use on my delta printer.
I recently bought a Micromake Hotbed for the delta and i am in the making of new covers to suit my needs with that haxagon heatbed.
Those cover plates will also have an option to align the glass plate and keep it in place while printing.
