Summary

Smile Key ring printed on the open school day @ PHTI Hamme.
As they where milling in alu on the 1st floor, we where printing a simular key ring on the 2nd floor ;-) This was to show the people that the product could also be made without chips or any other leftover.
The print was build with 45% infill meaning using less material to build a product.
smile4_5.stl is to produce 5 in a row.

Enjoy,
