You can download an 3d Print this model if you lost your wingnut on your air filter of your Toyota Conquest/Tazz.
Just 3d Print and pop a M6 nut in the hole, and it's ready for use.
See attached photo's in the renders.
For STEP, IPT and SAT downloads, see Toyota Air Filter Wingnut on GrabCAD.
See the images for my own makes.
