Bifold Door Spring Pin Hardware Replacement Rod

My Laundry door closet guiding rail hardware broke and replacement hardware didn't seem to fit without additional modification. On top of that, it was like $30. I took some measurements and replaced the spring pin. I had to compensate for both the missing spring and the distance it left in the door assembly. This glides nicely and now my door closes correctly. It was also a nice exercise in 3D modeling or design or something.
