Total design time in Google SketchUp: About 100 hours.
Total building time: About 300 hours.
Total printing time: About 50 hours.
All printed parts are printed on a: RepRapPro Huxley (Beta) 3D-Printer.
There are six 16mm glass balls in total in the sculpture.
Only one ball at a time rolls on the track.
The motor turns 1 rpm, then it's geared down a bit more so one turn on the elevator takes about 5 mins and 32 secs.
The ride for the ball from start to end takes about 1 min and 30 secs.
This means that most of the time nothing happens except the elevator slowly pushing the balls upwards. This was one of the key elements of the sculpture. It shall not disturb you, but when you watch it, you will be impressed. :)
This was the rules I had in mind when creating this rolling ball sculpture.
1. The balls I use are either glass or steel.
2. The ball shall roll as slowly as possible on the track. It should never stop but neither be in a hurry, you should get the feeling of a VERY controlled track and roll.
3. Swirling the track should not be needed when they turn. If you need to swirl the track the ball is rolling to fast.
4. The sculpture should be soothing not stressful. Because of the speed of the ball and the controlled rolling you should always be able to follow the ball and not have to concentrate to much to figure out whats next.
5. The sculpture should be as quiet as possible. You shall never be bothered by the noise. You should be able to have the sculpture in your living-room or office without noticing it if you are not watching it.
6. The track should be as complicated as possible on as small a space as possible. The more complicated the better, a long track on a small space is more impressive.
7. The track should always be two rails. Keep the track as modest as possible, simple construction is better then advanced. The less material used the better.
