UPD 24 dec 2019:
This is my project of 3d-printable delta diagonal rod hinges for standard Anycubic Kossel Linear Plus effector and carriages. Hinges are for 10mm steel balls: for example
I used this rods:
Pay attention to DELTA_DIAGONAL_ROD value: for hinges 21 mm and 200 mm rods it is 242mm (printing area is about 210mm!). For hinges 30 mm it is 260 mm (printing area is about 230 mm!).
21 mm or 30 mm means the distance between center of steel ball and rod connection.
It is also important to eliminate rods rotation around its axis to reduce the risk of fly off.
I recommend to print hinges with long ears for this or use anti-rotation bearings.
I also recommend to add some grease in the hinge-ball connection.
I use springs from this kit:
