Micro K’nex replacement roller coaster chassis
Description
This is a model for a replacement Micro K’nex roller coaster chassis. This has been designed to fit one of my LEGO/Knex car bodies on top of. The hooks on the front & back have been designed to be able to attach multiple of these together to make a full roller coaster train. For smaller trains like the Eurofighter I’d recommend 2 chassis per train whereas for longer sit down trains I’d recommend 4 (1 front & 3 regular cars), any more can usually look too long. Each chassis requires 6 wheels & 6 wheel nuts To connect them together, tip the cars to 90 degrees downwards & slide into the gap (as shown in the 2nd image). This has been designed so the chassis cannot come apart whilst on the track. To attach the wheels side a wheel onto a bolt end & attach a nut I haven’t been able to test this myself so I cannot be sure this works, however I believe it should, please let me know if there are any issues, especially with joining & unjoining the chassis together as it looks tight from my view. I’d also like to credit Aubenc for the nut & bolt pieces: https://www.thingiverse.com/thing:8796 All measurements in centimetres (cm).
