Intercooler key ring (IC Turbo)

Intercooler key ring (IC Turbo) pendant
If you want to do this witout my brand on back, just simply use one color (.3mf file for bambulab printers included with best set-up of lines on top layers direction, walls counts, infill, ironing etc)
For .stl and cura / ideamaker or other slicer please use top layer pattern - and correct lines direction to make "intercooler interior lines" from top to bottom as in real, also ironing topmost layer looks good

Enjoy!
