1/6 scale model.
Please note that my models could be imperfect.
This model was optimised for 3D printing in 1/6 scale, so the finest parts are deleted/oversized. Despite of this, you still may have difficulties to print the finest parts.
Be aware, the thin ring near the explosive charge is very hard to print. If you think your 3D printer can't make it, I uploaded another model without this ring.
