Thrunite TN4A Diffuser

thingiverse

This diffuser attaches securely to the Thrunite TN4A. The print has small beads at its base that enable it to snap into position in either the first or second groove of the flashlight. Initially, it might be difficult to place, but as you insert and remove the diffuser repeatedly, the beads will wear down to a precise fit, designed to be slightly larger than necessary for long-term use. When installing, you should hear a distinct "pop" sound when it locks into position.
