Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit 1e50952. 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 files0/20
No printable parts or CAD files.
Most points to gain: Add the parts to print (STL or 3MF files). Add the CAD source (STEP, or the CAD program's own files) so people can change the design.
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.
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.
Software5/15
Code in this repository. The documents have not been read yet.
Say which software framework it uses (ROS 2, LeRobot, Arduino…).
Documentation15/15
README of 3,145 characters with 2 pictures; 3 build 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).
Licenses10/10
Hardware: MIT; software: MIT.
