S.M. U-1 (a new RC project)

I continued with the lower hull and added the propeller shafts and their supports. The supports are 3D-printed. I was clever enough to mark the positions on the masters where the support struts meet the hull and where the shafts run through the hull. So no big marking issues on the glass fiber parts, just drill and glue. Fixed everything with super glue and the cemented the shafts into place using epoxy.

What I like about 3D printing is the flexibility it provides to make quick adjusrments. I gound out that there were feedthroughs where the propeller shafts left the hull. So I made CAD models of them, printed them, and here they are. Quick and precise.
