This is a quick and dirty set of feeder and vent tubes I made for a lost PLA casting experiment I have been working on.

This is a quick feeder and vent setup I made for lost PLA casting. For me, I print these, attach them to a 3d printed model I want to print. Then coat it with joint compound, let that dry. Encase it in sand with sodium silicate. Let that harden. Then pour in molten aluminum. The aluminum melts/burns out the PLA, leaving a cast object. I thought others might be able to use these. You can print multiple of the vent and attach them to make longer feeders/vents.
For an example of this casting process watch this video put together by someone much better than I at it. ;)
Enjoy!
