Made with 3D printed marketing gadgets in mind. 

Preferred thread length is something around 120cm (before assembly)

Assembling this is rather simple - just put end of the thread of your choosing into the mounting thread and then firmly thread parts into each other, using integrated clockwise thread

If you have any trouble threading these up, just try to shortly thread anticlockwise before threading clockwise to get parts lined up with thread threaded inside the thread

Feel free to cut out graphic of choosing onto thread-covering parts

Print settings (preffered, but kinda importante)

• No gap filling
• Concentric filling of the bottom layer
• Filling the upper layers with the Archimedes Spiral
• Fill 100% with concentric (at least with PLA (~1.3g/cm^3), but since it's YoYo usually denser is better)
