18650 mod body blank. This is what I used for the mod pictured below. I do have a lathe but can be done without one. Perfect fit for the battery when you use the plascic insert filter. (have to cut the filter out (easy). You can order the threads in 3/8 opening or 1/4 inch. I had the one for 3/8 pipe threads and the Lowe's hand brass nipple I used to but the battery conector in. Would probably work witht the 1/4 inch thread and not have to buy the part at Lowes just have not tried it yet. Here is the link where you can get one if anyone wants to try. I like mine. Last shot is with a different button. Pneuguard In-Line Filters & Dryers | Inline Pneumatic Filters — Walmec North America
