3D printing or additive manufacturing is the construction of a three-dimensional object from a CADmodel or a digital 3D model.[1][2] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control,[3] with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping.[4] As of 2019, the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term additive manufacturing can be used synonymously with 3D printing.[5] One of the key advantages of 3D printing[6] is the ability to produce very complex shapes or geometries that would be otherwise infeasible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight. Fused deposition modeling (FDM), which uses a continuous filament of a thermoplasticmaterial, is the most common 3D printing process in use as of 2020.[7]
The videos above show where we are and where we are going with 3D printing.
01 - Bolt Connector
You will be designing a connector for at least 2 bolts.
This video gives a step by step for the project.
Bolt dimensions:
40mm thread length, no shank
6mm - bolt diameter
the nut is 5mm wide
Your design must be less than 75 mm in any direction
It can be exactly like the one I make in the video
It has to connect to at least two other connectors
When you finish making your connector, turn your file as an STL ( Millimeters / Binary ) to the assignment. You will need to install an extension to SketchUp so you can "Export STL".
- watch the videos to the right
or
- follow the instructions in the sidebar to the right

02 - Toy Connector / Object Design
You will be designing new toy collage or vessel.
Where to begin:
The build plate for our MakerBot Replicator 2 is 150 x150 x 250mm or 6x6x10in. So your parts will need to be smaller than those dimensions or you will need to design your part in segments.
You will design your part in millimeters. Use the "Woodworking - Millimeters" template to start designing your part in Sketchup.
Save all parts from your speakers. Tape screws and small parts together with masking tape.
Give yourself plenty of room when you cut wires to resolder them.
03 - Speaker Design
You will be designing an adapted vessel for your speakers.
These videos give help designing the connectors for your speaker.
