For the upcomming Mardi Gras, called carnaval overhere, i made these keychains with the Grease car on it. We will go dressed up as T-Birds and Pink Ladies and these are some small give aways.
The rings come from Aliexpress. The keychains are printed in two colors and the colorchange has to be done above 3 mm.
The ones on the picture are printed on Glow in the dark green and the car in red. The Glow in the dark cannot be seen in the picture but it is the white part.
They are printed with 20% infill an 0.2 mm layerheight. No support needed off course and neither a brim is needed.
Have fun printing them if you like.
