This is created from the "Cat stencil" by Longquang I added a solid layer behind the actual cat so I could put it near a door frame. After I printed it I held it up to my monitor and realized it need a veion that could be stuck on the back of an object like a monitor of furniture. So print the one you want. Printing it in two colo? The back layer is .6mm so if you are printing a .2mm layer height your color change will be at .8mm. I chose white as a background but it would look good in many combinatio. There are some overhangs around the edges so print with support from plate. It won't add much. I extended the whiske depth so no support is required there. RIGHT or LEFT mount Flush or rear mount LIGHTBOX OPTION I have added several lightbox optio. You print the box separately with the door of the thickness you choose. I printed in a dark color and added a white sticker for reflection but use your creativity and have at it. I used a section of 12V 4mm LED strip mounted on the door. Lightbox Choices Pick LEFT or RIGHT Pick the Thickness of the lightbox 5mm, 8mm or 30mm Select the Door for the thickness you pick. The lightbox is Glued. I recommend a GEL glue with glue at all the corne. Remember to not glue your door shut. I added the 30mm because that looked to be about how far the light needs to be back from the surface to mount the light in the center and not have a bright spot. I only printed the 5mm. The lightbox option was designed for the rear mounted cats. There are two lightbox door styles. One sets back the other sets at an angle to cast the light upward into the cat.
