Camera Gimbal Upgrades

A while ago I made:

(remix search isn't working so I can't add it there right now)
as I've worked with it I found my nema17s to be a little underpowered and would occasionally drop steps. I decided to upgrade the pan and tilt to use helical gears and nema23s with the associated larger mounts.
all other parts as original thing.

I've also included the 'zoom mount' bracket that I use to mount a nema17 on a right angle bracket to provide a belt drive for the zoom ring on my lens
