Say hello to ARA, the stroller attachment you never knew you needed but now can't live without! Its modular design lets you attach as many rattles as your migraine can handle ;)

 

Assemble it any way you want - there's male parts, there's female parts, and if you want to put two female parts together, there's even an adapter for that. If you want to put two male parts together, you're unfortunately out of luck, since the opening on the back of the male part is too loose to get any kind of friction fit. Worry not though, there's a female version of every part so the male parts aren't missing out.

 

See it in action:

 

Feel free to make your own custom attachments, the dimensions below should help:

  • Ball Joint outer sphere outside diameter: 100mm
  • Ball Joint outer sphere inside diameter: 96mm
  • Ball Joint inner sphere outside diameter: 95.8mm
  • Screw: M20x2.5
  • Clamp inner diameter(also the shaft outer diameter): 30mm

 

Disclaimer: My printer is out of commission so I haven't had a chance to print and test these parts. I've done a bit of simulation in F360, but I'm an F360 noob. I will update this page with more information once I've had a chance to print and assemble everything

 

Thanks and enjoy!
