Week 10: Physical Models

Dealthly Hallows Sign

Software: Adobe Illustrator

Material: Acrylic

Digital Fabrication Tool: Laser Cutter

Recut. This time it has this bar for the LED to sit on.

This stops the LED from getting stuck on the battery and therefore is removed with the hallows sign so it can still act as a switch

Sphere Base
Software: Autodesk Inventor
Material: Plastic
Digital Fabrication Tool: 3D Printer

Printed in black because it was the printer available at the time. 

Printing this model hollow created a few problems. The scaffolding that was printed to supported the top of the sphere was printed quite solid. It was easy to detach from the model but because it was so thick I couldn't get it out of the model. Thus the broken off side.

The bottom of the model. The scaffolding for the top of the cylinder got stuck in there so the insert doesn't fit in its hole all the way. This means the insert doesn't use its bayonet fitting

The bayonet fitting in the base of the sphere. It printed really well to my surprise, considering its dimensions.

Insert One
Software: Autodesk Inventor
Material: Plastic
Digital Fabrication Tool: 3D Printer

This one wouldn't fit properly, it was to wide including the knobs. It got stuck halfway in and there was no way to get it out easily. I had to use extreme force

 Insert Two
Software: Autodesk Inventor
Material: Plastic
Digital Fabrication Tool: 3D Printer

I reduced the diameter of the cylinder and the length of the extruded pins out the sides. Doing both of these things made the insert quite loose and floppy, so it rattled when connected with the sphere. But the bayonet fitting still worked and kept the insert in there

On the bottom I put a little piece to pinch which enables you to twist and unhook the insert with ease. It works well
