3D model for a flask/ cope and drag.

Roughly 5.75"x 5.75" x 6" of volume for sand

Regular PLA works great, just keep in mind that you want to keep your cavity and sprue as far away from the edges as possible to keep from melting it.

if there is a high demand for the CAD files I will upload them, I do plan on making some match plate patterns for this as well.

the pins take 1/4 20 bolts and nuts, specifically 2 bolts and 4 nuts. 2 nuts and bolts should be embedded into the cope and the last 2 nuts should clamp the 2 halves together.
