This is made to be compatible with my other model set that includes a casting flask.   It should fit most ring sized flasks.  Measure and compare before printing your own if using another flask.

I've seen a few versions of this concept around the internet to help in casting precious metals by rapidly evacuating the gasses as the metal fills your molds.    The air mattress pump I used does a great job with the base attached to the intake of the pump.   

I will likely add another adapter for a hose to make it easier to set up on a work bench.

I've uploaded the model in parts and a whole version.   You can slice it as needed to accommodate your printer.   

I used a healthy helping of CA glue to put the parts together and had to sand a little to accommodate some warp I encountered in my initial print.  

As always I have included the fusion file should you want to tweak it for your own designs.
