Motorized Marble Castle a cute Ø14 Marble Machine
I proudly present the complete new designed motorized Marble Castle. An easy printable & nice looking, full functional desk toy.
This cute little model uses the motor from Anycubic's Motion Kit to assemble a USB powered marble machine.
The Castle is based on my Marble Castle D14 Desk Fidget Toy, but in the end i have changed all parts except the roof, to get a smooth infinite loop.
For the motion of the stairs a motorized crankshaft is used and the movement from house is managed through a worm gear with 14:2 reduction.
It is designed for balls with a diameter of 14mm, but any ball with a diameter over 8 should work.
You can insert more than one ball into this little marble machine.
Assembly:
For assembly you need
- Every part printed once (You can decide House with one or two entrance)
- A piece of 1,75mm Filament as axle
- Motion Kit Motor 5v
- Marble/Balls
