This is a Mount vor a Hongshikang Camera 90x15 camera module on 2020 extrusions.
Use two m3x8mm screws to screw it to the extrusion and 4 m2x10 self tapping screws to screw the cover and camera in together.
I used this one: https://de.aliexpress.com/item/1005004059029586.html
You can ask them for specific length cable while you ordered. I got a 1.5m cable with mine instead of the 1m default one.
For my 300mm Trident I think the 1m would've been fine, but I am not sure.
I think that all of their 90x15mm modules should fit, but I have not tested it.
I am currently searching for wider angle lenses, If anyone has a suggestion, let me know.
120° should be fine to get the entire bed, with the default one you will be missing a bit.
