Simple model to mount these https://a.co/d/j3AfXrr to the X axis arm on the Anycubic Kobra Max for DSLR timelapse.
Use double sided mounting tape on the 3 flat surfaces to secure it. This sits right at X-400mm. My printer will not go beyond 402 (firmware), but 400 is fine. Cord for camera shutter mounted halfway up vertical support, allows travel to very top of Z.
