Mazda MX5 NA/NB floor mat bracket

thingiverse

This is a bracket that keeps is place the OEM driver's side floor mat. Sometimes it gets lost but now you can print one easily for yourself in about 1h15min with 10grams of material. It has a hinge inside that permits to rotate the little blocker on top, just like the OEM thing, but you still need an ordinary clip to fix it to the ground, in the hole under the seat. I think PLA will do the trick here but you are free to experiment with other materials.
