Goals:

1- group assignment: test the design rules for your 3D printer

2- individual assignment: design and 3D print an object that could not be made subtractively; 3D scan an object (and optionally print it)

Individual assignment - Non-subtructive designs

First design

I used Makerbot machine to print the part.

Using fusion360 I created a sketch by making a hexa shape and then using "spline tool" to create the random line:

Then, by using "extrude" tool I extruded the sketch:

Using "shell" tool I created a shelled model with a wall thickness of 3mm:

I used "maker bot" software to edit orientation of the model and change printing setting:

Second design

I made this design by sketching a hexa shape and extrude it. Then draw a hexa shape on one of the faces and pockcet it through the model. As shown in this picture:

Then, I added a "trous" to look as a ring:

Here is the printed part; which looks nice:

Group assignment: Testing design rules for 3D printer

This is the surface finish model file stl. Here is a picture of the model while it's being printed:
