This is an add on for the front of a round torch style light to help diffuse some of the forward light sideways. This is a great feature when using a torch as a bicycle's front light and enables visibility from the side. A great safety aid in these dark winter mornings and nights.

The diffuser has been designed for my 35mm diameter torch. Just scale accordingly for the diameter of your torch, tip: wrap sticky tape around the diameter of your torch to increase it's diameter if required.

Print in white, natural, pearl etc for forward facing bicycle lights.

I printed without support because my printer bridged successfully between the four webs as the inner core started to be printed, however a raft was used to help the thin walled section adhere to the bed.
