This display rack was cut using a Full Spectrum 45W gen 5 Hobby laser. Finished parts were treated with polyurethane thinned with mineral spirits. It is important that the material used is 3mm thick. Otherwise it won't fit together properly. Design was done in Inkscape, so I recommend opening with that program. I have not checked it with other programs such as CorelDraw, but I have experienced strange scaling issues with going back and forth with other projects. One known issue is that the slots in bottom pieces are slightly too wide. It still fits together well enough that I haven't bothered to fix it.
