MR2 AC Fan Speed Control Knob

thingiverse

This is the knob for the AC Climate control in the Gen 2 MR2. It replaces your old knob, comes with a small section for light to shine through just like the OEM knob, and gives you the freedom to customize its finish however you see fit. I achieved the matte finish by sanding, acetone dipping, and then sanding again. If I were to print it again, I would face the knob upwards, but be cautious of the supports that will form on the bottom. There is a small metal insert in the old knob that needs to be inserted into this new one. Alternatively, you can use your favorite CAD software to close off the space between the two triangles.
