Gravitrax Gauss Canon with new Connector - no supports

thingiverse

I mixed up the bottom of this Gravitrax Gauss Canon https://www.thingiverse.com/thing:4163529 with the connector and notch of this spacer https://www.thingiverse.com/thing:3510861 so it dont need supports to be printed. You can print the connector and the canon part straigt sitting on the printer bed. Maybe you need to file of a liitle bit the outside of the connector. Works great with PLA. I have a printer nozle of 0,4mm and used 2 perimeter-lines and also 2 solid top and base layers. ##### Tip: Adaptive slicing I testes adaptive slicing, started with 0,4mm and go down to 0,15 where the track starts, for some layers, than back to 0,4 and again 0,15 just the top, to get a perfect round shape. Printing time about 40 min. at a speed of 60mm/s. ### The magnet For the Magnet use a round 15x3 mm Neodym. The fore of n52 magnets is a bit stronger than the original gravitrax magnet and the marble sometimes jumps out of the track. Tip: Put 3 Marbels behind the canon to reduce force. I also used a 2mm n45 magnet, but this has to little power to work well.
