Banshee Rune V2 Bottle Cage

A project for one of my postgrad modules. I designed, printed and tested a bottle cage for my mountain bike. The project hypothesis was for a low volume bike frame manufacturer who wanted to use additive manufacturing for the bottle cage; there isn't much space elsewhere in the frame due to the shock in the front triangle. I used reference images and measurements to create a frame model, which was then used to design the cage geometry. The part was designed to be printed as a single consolidated assembly to minimise extra manufacturing steps, and with the minimum of support material. Print orientation for strength was also very important, and it maximises the strength of the part in the XY build plane (along the layers) to clip and hold onto the frame and the tool container. This is a very good example of design for additive manufacturing, optimising around all the constraints of the process. It was printed in Polycarbonate for strength and toughness. This fit first time on my large frame very snugly. My dad has the same frame but in size XL which has a slightly longer geometry and so the slight deviation made it loose, so it really only fits the large frame. It lasted several months before it broke in a big crash, and there are a few minor improvements that could be made e.g. holes to strap/ziptie to the toptube (and improvements to the polycarbonate printing settings), but I have not come back around to this project yet.
