Hello,
My name is Zach Thomas. I am an industrial designer. I would be able to make these bright green door knob covers for you.
I can make these 2 different ways:
-I can print these on the 3D printer, using ABS plastic, PLA plastic(natural/eco friendly) or out of silicone. There would be small lines (.3 mm) on the surface of the part from the 3d printing process.
-Or I can use our thermoformer to get a smooth surface, with polystyrene.
Let me know if you are interested, or have any questions.
Best regards,
Zach
