Marble track - 6 balls starter (or 12) (Gravitrax compatible when using my 6 exit basic tile)

prusaprinters

A magnetic starter to release 6 balls (or 12) at once to kickstart an amazing marble run! Two versions included, one for 8x3 magnet discs and another for 5x3 magnet cylinders. I've not tested the 5x3 design yet because I only had the 8x3 magnets in my toolbox. The spring must have an inner diameter of at least 6 mm and the outer diameter must be smaller than 12 mm. You’ll need this part to put the inset in: https://www.thingiverse.com/thing:4237515 See this video for a demonstration: https://youtu.be/GHn4nCx018Q [Update 2020 may 24] I've tested the 5x3 magnets and it works fine for 6 balls, you'll not get the 12 balls to stick. What I found out was that the batch of magnets contains variation, so make sure you pick the strongest ones! The ones I received could be used without glueing them in. If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design. Thanks, Enjoy!
