Bolliger & Mabillard Floorless Dive train body for LEGO/Micro K'nex

thingiverse

This is a model of a B&M Floorless Dive train designed to attach to K’nex roller coaster cars for LEGO riders. Parts: For every K’nex roller coaster car you will need 2 car bodies, 6 restraints and 6 axles. Application: To use this, remove the coloured top parts of a K’nex coaster car using a screwdriver and attach the new train body onto the black chassis using adhesive, unfortunately this model does not have holes to attach using screws. There should be 2 of these train bodies per K’nex chassis so one over the front wheels and one over the back leaving a gap in the middle for the pivot axle. The bodies are larger than each of the halves of the chassis so will overhang however from experience this should not be an issue. A demo image has been included to show where the models should be attached, note this image does not feature an actual image of this model. Restraints: To attach the restraints, place over the seat and slide an axle into the gap. Both classic ratchet & newer vest restraint have been included so you can choose which one you’d like to use, both will fit the seats. I haven’t printed this myself so have listed this model as work in progress as I cannot be certain it will work but I strongly believe it will. The model should be to scale and the restraint has been designed to fit around a LEGO figure securely whilst leaving enough space for most LEGO hairstyles but not all will fit. There should be enough friction in the restraint axle to hold it securely however if it is too loose then you will need to increase the diameter or the axle slightly. As this design originally belongs to Bolliger & Mabillard, I can only give permission for non commercial personal use. All measurements in centimetres (cm)
