Marble Castle - REWORK D14
I proudly present the complete new designed Marble Castle. An easy printable & nice looking, full functional desk fidget toy.
Push the button to let the marbles climb the stairs and turn the knob to let them go out of the house.
A endless fun desk fidget toy for old and young!
Some new features and rework to my old model
- now for Ø14 marbles (Perfect for the marble run kit 003 balls)
- added a tunnel
- completely redesigned with brick structure and balcony
- gears instead of rubber band
- no spring is needed - lever and gravity works perfect
- “secret” marble compartment at the backside
- Castle includes the base, all functional assembly from bottom
- All parts are fixed with press fit connections
I added a print profile with a bit of coloring of the castle (decent filan´ment changes), you can paint it in slicer even more. But you can print the castle in single color as well! Even then it is beautiful!
The second print profile is identical, but with 0,1 layer height in track section for better marble rolling.
Assembly
Have fun with this design! I hope you like it!
