Terraforming Mars playmat overlay trimmed to fit Ultimaker3

This is a version of mrjymm's Terraforming Mars playmat (Which is based on designs by bombmk and 3D-Dave).

In order to get this to print on an Ultimaker 3 I had to trim a little off the sides to get it to fit on the build plate. All I have done is reduce the frame width while attempting to maintain the nice rounded corners. It is likely that this has weakened the frame so if you are able to print the larger model probably a good idea to print mrjymm's design.
