I made this replacement slider for the upper track of a bi-fold door. Because it does not have a spring mechanism it requires at least one good slider with the spring to be installed on the opposite door.
I recommend that you print it using Nylon or Taulmann Bridge or TPU. Nylon or Taulmann will have low friction and good long-term durability.
15% or higher infill.
