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:

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.

Update 30. Okt. 2022: Added YoyoBase Model for support-less printing

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)
• no Supports needed for YoyoBase

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 holded 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 used some minutes
