Sofirn Sp40 Short Tube Headlamp Holder

This is a headlamp holder for the Sofirn SP40 to be used with the shot-tube for 18350 battery. It is designed to hold the light in a "center-fire" position so that you are looking the same way the light is. It is also made to let the lamp twist up and down easily, and to let the lamp be easily removable. I used the Weltool Replacement Elastic Headband strap. I recommend using MJF. SLS fine too. This model can be printed FDM but requires strength in all three directions so I wouldn't use it. The headband mounts are split so this is "no sew" but that makes the pins weaker.
