Description
I made this model as a newbie to the world of FreeCad and 3D Printing. It is designed to hold 12 car-type spark plugs for when servicing a Lycoming IO540. It should print well in a filament that can withstand the heat from a hot plug (PETG, ABS, ABS).
If you prefer a similar item in the same layout as the engine itself then check out my other version HERE.
Post pictures here if you print it and let me know how it goes.
