Parametric Sand Casting Tools

Parametric sand casting tools, including Fusion 360 file.  Includes 3mf files for a sprue, swirl pot and two runners; one each with and without a swirl pot.  The swirl pot has a locating hole designed for a ¼" dowel.  The sprue is best printed laying down so I have split it into two parts, you will need two of these, then glue them back together.  I sand mine with 80 grit, then 120 grit and pain them so they're smooth.

I'd appreciate feedback to improve the models.

This is a work in progress, you will waste filament at your own risk.  I have printed them and they do work for me, but you may have to adjust the tolerances.  You can adjust the sizes of everything using the ‘Change Parameters’ in Fusion then export as a mesh to print.
