This is the rig that's still assembled. It doesn't use the carbon seat, and it's a better rig without it.

The second rig
I don't sit in the carbon shell. I sit in a padded reclining chair on a second rig I built later, and the photos of it are from April 2024. The chair sits on a wide, low base instead of a narrow frame. Making the shell was a better exercise, but the chair is better to sit in.


Sheet 03 of 03/What changed
The wheel deck
The clearest fix on the second rig is that the direct drive wheel base bolts straight through its own timber crossmember instead of clamping to the edge of a desk.
