These two fellows wearing typical noseguard helmets are the first in a number of seated oarsmen who, together with a standing coxwain make up the crew of a Viking Warship. I originally designed them to populate the small 24-seater in my other post. But, theoretically, you could also populate a 64-seater like Olaf Tryggvason's famous Long Worm, were such a model to exist. Full size is 1:72 scale so they are pretty small.
Each pair consists of a left hand and right hand version of the same oarsman (I found it helps to print them in pairs to keep track of when populating a boat). The pairs are easily printed out in 30 minutes using a 0.4mm nozzle and 0.15mm layers. For more detail, use higher resolution but that will increase the printing time to about 90 minutes per pair. Supports are necessary for the legs if you print them out lying on their backs.
