This is an aluminum frame with an inside cavity where you can pour in epoxy to make your own mold. The frame has two steel pins and holes to keep the two halves exactly aligned with each other. The rear panels of both halves are removeable.

Once the epoxy mold is cured in the frame, it can be removed in order to use the frame to make additional epoxy molds. You can also use this frame to hold 3D printed molds.

Outside Dimensions: 5.0"W x 4.0"H x 2.0"D
Inside Cavity Dimensions: 3.875"W x 2.875"H x 1.5"D
