I made this out of the last uploaded model, it would be cool with track peices, and a cart. but, its good, supportive, and its used on K'NEX Roller coaster sets.
To make something similar, Download the previous model, and explode it. From thier, you copy and paste the peices until you've made a model. upload it and comment me if you want me to see it. Good Luck! #Box #Comment #Connector #KNEX #Rod #Support
