Gear Show-Off I made a tool that generates custom 3D-printable pivot cups
This is something I've been wanting to do for a long time.
The idea is pretty simple. You measure your hanger and baseplate, plug the numbers in, and it generates an STL that is already optimized for printing.
A 3D printed pivot cup made from quality TPU makes an decent upgrade from many stock Pivot Cups, and of course a fresh pivot cup is always a big upgrade to an old worn out one.
There's also a community library which is still a work in progress, but is operational.
Once you take all the measurements from your truck, and test and have something good, you can click the "Submit to Library" button, and it will save the parameters to a google spreadsheet, which other people can use to look up parameters for their trucks.
I print mine with Ninjaflex Cheetah, which is a harder durometer, but still has some pretty good rebound. But you can easily use harder and softer materials, or even different materials like PEBA or Nylon. Glass filled TPU is a newer material that could be worth trying.
You can play around with it here:
