About this 3D model

I use wood chips in my smoke tube, and needed a better way to fill it. Here are two funnels for a Hexagon Smoke tube. One fits "inside" the smoke tube so chips that are exactly the size of the opening will not go in (because the funnel is inside and takes up a little space). The other fits on the outside of the tube, so it can be filled with wood chips as large as the mouth/hole of the smoke tube. The "inside" funnel fits a mouth opening of 37mm. The "outside" funnel fits an tube that is 51mm. You can resize if you need them a little bigger or smaller.
