Screw threads might be stiff at first. Try to tighten and loosen cap to vial repeatedly to smoothen threads. update Added 18650 tube.stl & 18650 cap.stl This is designed to store 1x Fenix 18650 or 2x CR123A batteries. update Added "18650 v3 Assy.stl" A rubber O-ring (ID 20.3mm, W 2.4mm) can be used.
