Free plan for use on a laser machine.
The plan is adapted for 3mm (1/8 inch) plywood.
Step 1: Creating a Template
Usually for simple projects we use 2D editors like Corel Draw. This is sufficient for models including 3 - 20 pieces that will be connected after cutting. To test connections, you can use the simplest 3D editor - Sketchup. It does not take much time, but you will be sure that the cut parts will be assembled correctly.
So we have drawn a layout and are ready to send this file to a laser machine. A couple of minutes all pieces are ready.
Step 2: Assembly
It remains only to assemble all the parts and glue all the grooves. The whole model consists of three parts, so I will not go into details and make instructions.
