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

thingiverse

You will need a magnetic starter to release 6 balls (or 12) at once to kickstart an incredible marble run right away! Two versions are included - one for 8x3 magnet discs and another for 5x3 magnet cylinders. I haven't tested the 5x3 design yet because I only had the 8x3 magnets in my toolbox with me. The spring must have an inner diameter of at least 6 mm and the outer diameter must be smaller than 12 mm. Watch 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, but you won't 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 gluing them in. If this project helped you, please donate what you think it's worth on my paypal.me account. Help cover the time spent designing this project. Thanks for your help and enjoy using this magnetic starter!
