Model created in Zbrush. It is watertight and ready for printing/milling. Model is split into parts for easier printing and casting. There is also a merged model included (all parts put together, without the spear). In default size, diameter of the spear is 1.5 mm, which should be enough for safe printing. Please be careful with scaling the model down too much, unless You are sure You can handle the fragility of the thinner parts.

Each model is provided as a triangulated STL and OBJ.

Default size (although easily adjustable in any 3D software) is:

width: 92.5 mm

height: 150 mm with spear / 124 mm without spear

depth: 72 mm

volume: 50 cm3

Please note that the model is solid. For hollowing and saving material, I can recommend Meshmixer as an easy and free tool.
