The Model includes different kinds of marble-run-pieces for 1/2 inch bearings compatible with the popular wall organizing system Multiboard.
In order to use the different pieces I'd recommend first printing out some big enough plates and any kind of wall mount or freestanding pieces. For me the freestanding options didn't work that well because the marble run vibrates a bit when a marble rolls through it. You can find any kind of official Multiboard parts on this website: https://multibuild.io/parts
In order to connect the pieces of this model to the plates you need to screw the marble-run-pieces to a Multiboard snap. You can use any kind of Multiboard snaps, but I's recommend the normal ones as they are omnidirectional. You also need any kind of locking bolt. I used the Locking T-Bolt for my marble run.
These are the pieces I made for the marble run (but you can design your own too):
Tilted Rail:
The Tilted Rail is used for marbles to roll down a slope and keep it moving. They are marked with an arrow to indicate the direction the marble will roll.
Curve:
The Curve is used to bring the marble down a tile and speed it up significantly.
Steep Rail:
The Steep Rail brings the marble down 2 tiles and speeds it up.
Marble Drum:
The Marble Drum is used to stop the marble from rolling. By a twist at the handle the marble starts rolling at the other side. You can also start a queue of marbles one by one. To assemble the Mable Drum slide the drum over the axle and secure it with the clip.
Stopper:
The Stopper can be used to stop a marble from rolling of an edge.
Vertical Pipe:
The Vertical Pipe can be used to guide a marble a constrained path downward.
T-Junction:
The T-Junction is used to guide a horizontally moving marble into a Vertical Pipe or onto a Tilted Rail. You can block off one side using the Stopper.
End Piece:
The End Piece is used for catching marbles at the end of a track.
Print settings:
Infill: 15% (Cubic)
Support: Tree organic (only for the Tilted Rail and Steep Rail)
Perimeters: 2-3
Layer Height: 0.2mm
Almost all the pieces (not the Marble Drum) are designed to be printed on the front facing face. This ensures best print quality for the threads in the back.
Notes:
On almost every piece there is a designated symbol which could be used to create diagrams of tracks to share tracks between users.
