3D model description

Model of the Dutch navy submarine built at the start of the WWII.

The 21 Class contains seven submarines still incomplete at the start of the German invasion of the Netherlands. Four of them (O21,O22,O23 and O24) escaped to the United Kingdom.

Unfortunately two of them (O25, O26 and O27) didn't make it so far and were ceptured by the German Navy.
All tree were ordered to complete by the Germans and entered service as UD-3, UD-4 and UD-5

The submarines were built at tree different shipyards:
The O21 and O22 at Koninklijke Maatschappij De Schelde in Vlissingen.
The O23, O24, O26 and O27 at RDM in Rotterdam and the O25 at Wilton Feijenoord in Rotterdam.

The O21 class was a very modern submarine and could compare with every submarine in years of the WWII.

The Submarine was equipped with a new Dutch invention the "Snuiver" but the conservative UK navy did'nt see the potential and removed them from the four submarines when they were completed in England. The Germans saw the possibilities and used the "Schnorkel" in the U boats in the second part of the war.

The O21 was one of the only 14 submarines who sank a German U-boat (U-96 VII C) in the WWII.

Specs:

Laid down 1937

Armamant: 4x533mm bow tubes, 2 533mm tubes in the Stern 2x533mm externel traversing midships.

The model is originally designed at 1/50 scale for RC use. The big one is not ready yet. I printed the -slightly modified- model at 1/100 scale for testing. It looks very nice and maybe some one would like to build a static model of this beatifull submarine.

I printed this model with Esun Pla Matte Basic Black on my Bambulab P1S printer and it looks very good.

Length: 77,7 cm
Width: 6,8 cm
Height: (With Stand: 155 mm

The images of the printed model are taken from the 1/100 version. A bigger 1/50 scale RC capeble version willl be uploaded soon. The printed and showed model is direct from the printer only glued together.
