This is a 3 piece "kit" that easily assembles into a single zech Hedgehoge used by the Germans in WWII. This model was used by following a 1939 drawing that was verified by photographs.
(By making the hedgehog model in 3 peices you save money as this model takes up much less space in the 3D printing machine whhich is calculated on volume as well as materiels type and volume.)
Assembly is easy, just cut from smalle end sprues and cement - instructions: HTTP://lewsmodelboatsorg/3D-models/Prod106-assemb-instructions.png
Availible in white tough plastic (for RC tanks) or detail plastic (for static/display models).
(More to come: multiple sets, other scales, etc.)
