I tried it with eken V5 doorbell but probably it will be suitable for many other types with similar dimensions. In design I have approximatly 3mm space between doorbell and cover. Cover allows fast disassembly by sliding it upwards.
65 x 128 mm
2.6 x 5.1 in
Let me know if find other suitable door ring type. Or you can type to discussion.
