myminifactory

rollercoaster that can be build with drinking cans 250ml in combination with 3d printing. for a working vieuw see the youtube link. you can start printing with the track en can connectors. Build it all together and than take a 3mm fillament for the rail. It will klick in to the rail parts. The rail is connected with parts that can be adjusted in the right direction. the cars can be joint togther by the car to car connector. you can place this by the bearings that are on the top op the track. Leave a little room so they can move with the track when the cars go down the track. i used bold and nust of M5, M8 and spacer ring M8. M8 and spacer ring for the bearings (608zz) and for the other connections M5. Best print and fit is with a ,35 nozzle ,2 layer heigt.   for the track you can sellect differend lenghts. The track part 3 is a flexible part that allows you to twist the track. This part you can also cut it to the richt lenght. the track parts slides together with al litte pressure. It is designed to fit tight. so it is possible you will need to sand it down al little bit for a good connection. I added some pictures so you can see how everything comes togeter.   enjoy printing and building your own rollercoaster.
