Suspension-Steering for Thule Jog Kit

Mounted between the wheel axle and the two “arms”, this adapter should fit single and double Thule chariot (not the newest above 2025 ones) jog kits. 

Printing:

• You'll need to mirror the CAD in you slicer, as these only work in pair! 
• Suspensions “plates” i.e. the compliant part, should be printed as outer walls and mind the printing direction (picture). It is important this parts is printed as continuous paths
• Use 100% infill where screws compress the part

Mounting:

• You'll also need 2xM8x20mm screws and suiting nuts. 
• Clearance hole for the screw is designed to be tight, so the screw will not loosen with vibrations
• Mounting is a bit tricky but i preferred adding more material for rubustness, you'll manage

I designed it to be approximately as stiff as one back wheel set at lowest stiffness (~0.5mm/daN). This allows for decent suspension as well as nice right/left flexure for steering; without loosing the advantage of the jog kit, being the chariot driving straight without holding it. 

It held the weight of a single version Thule chariot with <1y old, on forest paths for some while now. But wildly hitting curbs will probably brake it. I went nuts on the first version (shown in  pictures) to see when it‘ll brake. It took some load to brake and the newer version should hold up much better.  Nevertheles, it may snap so make shure this will not harm you or your little passengers. 

As far as i know it's the first solution for this purpose.

I CANNOT GARANTEE THIS PART WILL NOT BRAKE! USAGE IS UNDER YOUR RESPONSIBILITY!
