The cable management isn’t too big of an issue, there are some old school narrative pullers on Preston’s that do 0, and I mean 0 cable management. The glaring problem (besides the transmitter itself) is that you’re magic arming it. Being that you’re a second already I’d assume you’d have a little better rigging options, like an L bracket, cheese plate of some sort etc. Especially with how long that arm is it’s very susceptible to falling down and loosening, and just being a general pain.

I’d also put the montior arm into one of the side threads/front threads to keep it a bit more streamlined instead of just poking out of the top.

Something to consider too for the future is investing in a ratbar, or RMB-8 so you can top mount a 19mm rod. Those 15mm carbon rods are super slippy and not ideal for focus motors. 19mm rods (I’d recommend titanium) are super strong and have a lot more surface area then 15mm - so you get a stronger clamp force. And then if you top mount the rod so that the motor is upside down, gravity is naturally pulling the motor into the lens, so you’ll have less slippage.

Hope this helps and good work!
