Soft-box/ diffuser for canon flashes

I designed these two softbox sizes for my two different flashes. I am sure they could be modified to fit other flash heads. I am really pleased with the quality of light. I printed them at a 0.2mm layer height and five bottom layers. They are quite bulky which is why they have holes for clips on the sides. I painted mine and lined the mouth of the diffuser with duct tape to make sure my flashes do't get scratched.
