I have printed this at different scales, and at different infills.

I recommend 5% infill at the larger scales
Allows the buyer to print up to 100 copies for home use only. Purchasers cannot distribute or sell the printed items and they cannot distribute or sell the digital design. If they wish to print more than 100 copies they must buy multiple licenses.
it is less needed at the smaller sizes.
