This is a simple model of a surface submarine that can be used as a cake topper (cupcake topper). Silhouette resembles Victoria/Upholder Class submarines.
The submarine measures (L x W x H) 64.49 x 20.94 x 14.58mm.
This was a special request I received. I asked for the desired measurements and then sketched it in 2D (top view), extruded it, tweaked it, printed it, and asked for feedback. It took four versions to get it right.
