1/50 scale 3D model of the so called three cylinder diesel - electric submarine of the Dolfijn / Potvis class.

The Potvis-klasse where in service from 1965 till 1992 by the Dutch Navy.

The class contained 4 ships :

HrMs Dolfijn HrMs Zeehond HrMs Potvis HrMs Tonijn

The design was made in the late 50's and reletavely unique because of the use of a 3 cilinder presure hull. The intention was to place te more heavy parts (engine and accu's etc) in the 2 lower cilinders en the less heavy parts in the 1 top cilinder. This should reduce the need for ballast and use that weight to strenghten te pressure hull.

One of the Potvis-Class submarines can be seen at the Navy Museum in Den Helder in the Netherlands.

Model specs:

Detailed model designed to make a rc submarine. The hull has many detail and is separated bottom and top part for easy mounting a WTC (Water Tight Cylinder) Also separate dek parts, to be printed with your FDM or Resin printer for better detail. This model is specielly designed for RC use. If you are looking for a nice static model to build.. a less cheaper 1/100 model is also available here.

Length: 159cm Width: 15,6 cm

2 types of bow types (closed or open) with model mk37 torpedo.Seperate deck parts. (eventually to print with Resin printer)2 types of Sail, one without stairs for FDM and one with for Resin printer

Minimal Printbed size: 220x220x220(H)

I printed mine with PLA basic matte from Esun The matte pla gives a really smooth look surface makes it more easy to remove the supports, because of the many detail and holes in the hull it is needed to print with the use of support.After printing treat the hull inside with epoxy to make him better water and heat resistant. You can also print this hull in ASA (you need a closed 3d printer)
