So in the video there were two things that made me go ‘ahh that’s not really gonna fly for a mass marketed product’

One was the multiple beams at specific positions on multiple axles that require a lot of fine tuning.

Either you’d have to pack the axle with other pieces to make it fool proof or these would get out of whack over time causing issues.

The other (more problematic) issue IMO was the rotating mechanism at the top of the build. This seemed to use non-standard spacing by having rigid hose pieces connected to the 24 tooth gear.

Just don’t think that would ever fly and would need to be reengineered.
