I need help with a sight

I want a sight for some light tanks i have, the bradley, vilkas and LAVAD. I don’t know how to make it but here’s the reference photo. If someone who knows how to do user sights could make it or help me make it either way much appreciated. Im aware the wt live community gets asked often to do stuff but i have yet to learn and would be open to make it myself, just dont know how to.

Lots of custom sights already, plus there is a few topics on how to create your own.

ive found a way to make it on Sketchup but i cant use the extension to make it a BLK file and im trying to make it a blk file.
