Open Source Yoyo

This is a Yoyo with the logos of the Open Source Initiative and Open Source Hardware.

More Themes and the OpenSCAD file can be found in my github repo:

https://github.com/andimoto/theme-yoyo

Note: printing takes about 12 hours on Prusa Mini. It is very easy to design your own Yoyo with a custom graphic on it! Just checkout the repository.

Printing

• print ThemeBase on flat surface (graphic up)

• do color change at the graphic to separate it from background

• enable ironing on top layers the get a nice finish

• print resolution 0.1mm

• use PETG for stronger parts (of course PLA is also possible)

Parts

• printed YoYo Parts (2x yoyoBase_xmm.stl, 2x YoyoThemeX.stl)

• one M3x20 screw with M3 nut for Axis

• 8 M3x6 screws (cylinder head screw)

• 2 O-Rings 15x2.5mm

• R188KK Bearing

• Cord (there are ready Yoyo Cords, relatively cheap)

Assembling

• place the bearing onto the center of the yoyo base

• place the o-ring in both yoyo bases

• put both yoyo bases together (may be necessary to press them carefully together)

  • they should be held together by the bearing

• screw both yoyo bases together with the M3x20 screw (do not overthight the axis)

• screw the theme parts on top of each base carefully (do not overthight them)

  • tip: measure the weigth of the theme parts and balance them out with small parts of filament

which you can place into the furrow/gouge which are extra made for weigth balancing

• maybe the yoyo needs to be weared in some minutes
