Predator Fish box

Predator Fish sugar bowl

I wanted to make an unusual sugar bowl (container for small things) in the form of a fish head

Fish with cute teeth 8)

I decided that using a standard jar design (in the form of a jar with a lid) is not so interesting

For example, what is more interesting to unscrew (lift) the lid from the can? or click on the fins of the fish and it will sharply open a toothy mouth 8)

After sketching the idea, I started building a model in Cad Solidworks

I made the main shape from simple geometric bodies, set the required wall thickness and decided on the actual dimensions of the product

Then I went on to sculpting, I like to do this in the first stages of work - this gives freedom of form, but dimensions can change dramatically ...

When playing with product forms, I settled on the option presented below

But this is only a beautiful form, now it’s necessary to add mechanics to “revive” the model

I turn to modeling the mechanics of opening the mouth

Here are a few sketch of the development process.

The model is developed taking into account the features of the technology of 3D-printers FDM. Moving parts are printed as a single inseparable mechanism.

I made the parts that can break the spring and the jaw retainer separate and collapsible so that they can be easily replaced.

The model is developed taking into account the features of FDM 3D printing technology. Moving parts are printed as a single inseparable mechanism.

I made the parts that could break during the exploitation (plastic spring and jaw holder) in separate parts so that they can be easily replaced or changed in design / using different materials when printing ...

Despite my experience in 3D printing, the optimal geometry of the spring was not the first time 8) here are a few test options

The following are photos of the manufacturing steps - preparation for 3D printing and a ready-made model from PLA plastic
