Buildable with some effort

How complete the published files are for rebuilding this robot, measured by Robotheca at commit b2ff16a. It isn't a rating of the robot. Counted out of 80 points and scaled to 100: the parts that don't apply to this robot are left out. How we score

3D and CAD files20/20
47 printable parts (STL, 3MF), 57 CAD source files.
Robot descriptionNot counted
No URDF. Not counted: the score is made of the parts that apply.
Optional: add a URDF, and the robot can be seen in 3D and tried in the browser.
Parts list0/20
No parts list in the repository or linked.
Most points to gain: Link to your parts list, or add it to the repository (a CSV or a Markdown table) with quantities, prices and where to buy each part.
Software10/15
Code in this repository, built on arduino. The documents have not been read yet.
Documentation10/15
README of 3,826 characters with 5 pictures; 0 build steps.
Split the build into at least 3 steps.
SimulationNot counted
No simulation files. Not counted: the score is made of the parts that apply.
Optional: add a simulation model (MuJoCo, Gazebo, Webots or Isaac).
Licenses0/10
Hardware: no license; software: no license.
Add a license for the hardware (e.g. CERN-OHL-S-2.0 or CC-BY-SA-4.0). Add a license for the software (e.g. MIT or Apache-2.0).
