Bolliger and Mabillard Cobra Roll

thingiverse

Printable model of a B&M cobra roll. Model was designed with only appearances in mind and was not designed to be functional with a coaster train. You can either print the whole model as one piece or print and assemble seven separate pieces. Printing the model in pieces will take longer than one piece, but will greatly reduce the hassle of support removals and chance of breaking. Depending on the resolution of your printer, the connecting ends for each section may be too tight or too loose. Model is not accurate to the real thing.
