About this 3D model

A friend wanted a UK Merchant Navy plaque, so I tried to print one, I am new to 3D printing and even newer to CAD, which shows, but it was fun and I am happy with the finished product. Please share away or tinker with it as you please I just set it up for X1C 0.4mm standard setting on the PEI plate The second file is for the A1 0.4mm PEI plate
