Here's a diffusor for the Sofirn SC31 Pro flashlight, very useful to turn it into a lantern.

It can be put either on the top of the light to diffuse ligt, or on the tail when not used ; its flat end allows to set down the light on the diffusor.

The tolerance is really low, which allows not to put off the diffusor accidentally.

It's printed in white PETG (Sunlu), which is actually very translucent.
