Adapter to use the stock arms and ball-joints on the Flsun SuperRacer AWD with integrated tensioner.

I've designed 2 top parts one for a Direct Drive / Bowden setup and the other for Flying Extruder:

Direct Drive / Bowden	Flying Extruder

For the tensioner, I user a 40mm M3 and a t-nut, this will provide approximatively a range of 18mm to tension the belt.
You might also want to use 6 M3 grub screws to secure the ball-joints.
 

I recommend printing these in PETG or any strong materials specially if you intend to push your SuperRacer.
The location of the endstops remain the same, you might need to add a ziptie on the belts or these clips (https://makerworld.com/en/models/240711#profileId-256652) if you plan to apply a fairly high tension for high speed printing.
 

Thanks to the DeltaWerken team for the inspiration and discussions.
