About this 3D model

Hello there! Here is a US Army Lightbox, face down and the back plate just slides on the back! It is separated in two different parts and holes in each part so the led's can start in the bottom and go to the top portion as well. Here is the link to the LED strips i used. https://www.amazon.com/gp/product/B0BG885LVL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Let me know how it is!
