About this 3D model

I have recreated in 3D an old magic coin box that allows you to make a coin disappear or change in front of your eyes ? Assembly: Glue the top of the black box to the body. Insert the coin base into the black box. ♠️ Magic trick (This magic trick relies on perspective and gravity, so make sure to practice a little before performing): Prepare your gimmick by inserting the coin into the hole closest to the open wall of the box. Place your finger to cover the empty hole and allow the inner piece to slide. Insert the other coin into the empty hole. Slowly place the black box onto the white part. Remove the black box, using gravity to prevent the internal piece from moving.
