[Introduction]
Modeled after the toy from the 90s of the same name. It was one of those interesting little toys I had as a kid that I also have found memories of, and so like any nostalgia filled designer, I recreated a modern one.
[Hardware & Tools]
Featured Filaments:
Bambu PLA Basic Purple
Bambu PLA Matte Mandarin Orange
Bambu PLA Glow
Bambu PLA Matte Dark Red
Hardware:
4x M2.6x8mm Self Tapping Screws (Bambu's BT2.6x8mm self tapping screws)
2x MR128 Ball Bearings (inner = 8mm, outer 12mm, height = 3.5mm, such as this one from Amazon, or from the Bambu store)
Notes on the print:
I increased the infill density of the main body so it isn't too top heavy! I also have supports turned on for the main body, so make sure to clear out the supports and any material that might interfere with the string's path! I don't recommend printing the model without supports.
[Assembly]
Insert the bearings into the two pulley wheels.
Now install the pulleys and hook into the main housing.
Install the 4 self tapping m2.5x8mm screws
Now screw the 4 end caps on!
For the ball, it'll print in 3 rings. Just slip them over/into each other to create the ball!
Lastly, for the handle, tie a pie of string to the tie off point, and wrap an appropriate amount of string around the handle. There's a notch on the handle too, to help keep the string in place when in play.
That's it! Enjoy!
