You can use this model for commercial purposes an infinite number of times

Full scene and presets included, and obj files almost for each one

quad based mesh, for sub-surf or turbosmooth, solidify or flat modificator in blend files and obj version of model on thumbnail

I made several variations of the model in low polygon, high, with and without thickness I hope you enjoy it
