The CAD is located at https://tinkercad.com/things/issjkUuMiGI. It was built upon the foundation of another design found at https://tinkercad.com/things/6YG33TxYcvV. This iteration, v2, boasts a sleeker and more lightweight design, characterized by thinner walls and a shorter overall structure. To ensure that the carriage can travel all the way to the top, it's crucial to use either two standard fan holders or one large holder paired with a regular one. The large holder must be placed at the front side; otherwise, the carriage won't reach its full height. Standard fans are suitable for both back and front positions, while larger fans can only be used in the front. This particular fan holder is compatible with the carriage found here: http://www.thingiverse.com/thing:1521037. However, it's likely to work seamlessly with other carriages as well.
