Hotwheels wall display - 3 in 1 with solid back

I connected 3 of the hotwheels wall mounts together for ease of mounting. I then found the original honeycomb design was too weak to support multiple layers so ive designed it with a solid background as to create strength. Print profile is in HIPS material as I had some left over from another project.
