Magnetic 6 ball starter for Gravitrax- for 3mmx5mm magnets...
Description
So I love the starter by hd42 (thanks to his daughter's ideas), but I had troubles printing it. First of all, the walls under the Marble seats are too thin for my printer. Secondly, the 5x2 magnets are too weak, and do not hold the marbles well, but using the 3x5 magnets are too strong for his design. The base sits too far up in the housing when I have printed it I have redesigned this adding 4 changes. 1. The wall under the ball seats is thicker and more printable. 2. The button is designed to hold 3x5 magnets. 3. The base with the connector is now thinner to allow more depression of the release button. 4. There is a thin spacer that goes into the Button housing to make it so that the base PERFECTLY aligns with the bottom of the housing. You will need 1 spring...about a quarter inch to half inch wide. You will need 6 5mm by 3mm magnets You will need model glue or metal glue For your reference, there is a picture of the Starter that has been exploaded. You basically put the parts into the housing in that order. I printed this with layer hight of .12 with PLA.
