Cement gun filling funnel

thingiverse

As the title clearly states, I'm talking about a Cement Gun Filling Funnel. Recently, I purchased a "roughneck" cement gun and quickly realized that filling it would be quite awkward when using loose material - a process that could potentially waste a lot of time on the job. To make things easier, I decided to create this funnel to simplify the filling process. A scoop was also considered as an alternative solution. The small diameter of the funnel fits perfectly into the 50mm tube of the "gun". The length from the shoulder is 20mm. An additional 50mm extends to the cone. With these measurements, the total height of the funnel comes out to be 70mm. The overall diameter of the cone is 138mm. When printing this design, I had to turn it upside down due to the presence of a shoulder. Filling the cement gun with this new funnel has not been tried yet.
