IMT industrija Motora i Traktora Beograd. Keychain for serbian (yugoslavian) brand of tractors. There is complete keychain and also 3 parts of it to print in different colors so it looks like real logo. I printed with 0.4 nozzle and PLA. Every layer of color is 1mm so if you dont have two extruders you can print first layer with black PLA (IMT_SPODAJ.stl), then babystep +1mm for white (IMT_VMES.stl) and last babystep +2mm for red layer (IMT_ZGORAJ.stl).
