About

3D printing technology has been expanding widely through out engineering industry. All of us have heard of 3D printing is coming towards our daily uses, but have you ever hold on something that is 3D printed?

Eng Case is not just something that's 3D printed, its a combination of art and engineering design. It represents the trend of future fabricating technology. With the flexibility of 3D printing, I was able to make varies designs without worrying about the huge initial cost of moulding. Eng Case designs are comfortable in your hand, and fun to play with. You will find yourself spinning the gears while loading apps, and showing your awesome case every time you see a friend. Furthermore, customized tags makes your case personal.

My Story 

I have been using 3D printers for about 3 years, I have built varies kinds of RepRap 3D printers like Prusa Mendel, Prusa I3, Mix G1. Two years ago, when I started my university life at Queen's University, I learned to use 3D design tools. With the time in school, I mastered the tools and start to design simple things like repairing parts to complicated ones like components for my printer. With my experience with 3D printing, I was able to bring my designs to life, and I saw the power and possibility of this technology. 

 Few months ago, I started to design cases with working gears for my iphone. When I brought it to school, all my friends got amazed by the phone case on my hand, and told me that I should start a business with it. So here I am, after few months. I made tons of phone case designs, and wanted to share with you my best three.

 Design 1

Best looking design, with a gear rack on the side that motivates the gears. Sliding the gear rack will become your habit when loading apps. 

Tag on the top right corner can be customized with simple shapes or characters (maximum 2 lines and 5 characters on each line).

Design 2

A reversed engine design. This design transforms a circular motion into a linear motion. Its fun to see these tags going up and down, trust me.  

Both tags can be customized with maximum 5 characters on each.

Design 3

Not just rotating gears, but moving gears! A design with most gears and moving parts that rotate around the centre.  

Tag on the top centre can be customized with simple shapes or characters (maximum of 2 lines and 7 characters on each line).

Other Fetures

  • Glow in the dark! 

 Glow in the dark material does not re-emit the radiation it absorbs immediately, instead radiation is re-emitted at a lower intensity for a long period of time after being charged with a bright light.

  • Customizable tags
  • Available for iphone 4/4s/5/5s/5c, samsung s4/s5/note3, and nexus 5.
 
  • 3D printed! Everything is going to be 3D printed by me, here in Toronto, Canada.

I already have few machines ready, will build more if necessary. All these machines are from Mixshop.com, with 0.3mm nozzle diameter(smallest nozzle size out here). I will ensure the best printing quality for every single case. I will try to get all cases printed within two months of the end of this campaign. 

  • Professional packaging box, a nice and personal GIFT!
 
This is the main reason I in Kickstarter, I need a large order quantity of this box for it to remain in a reasonable price. I will make sure it looks nice and qualifies to be one of your best gift.

Overall Specifications:

Material: I will use PLA, an environmental friendly material for most parts, and will use glow in the dark PLA for all the gears and tags.

Colour: You can choose between white and yellow for outer case (might add more colours later), and we will combine with different colours for gears and background for best outcome.

Estimated shipping schedule: Depending on how many cases I will have to make, I will try to build enough machines so that I can finish printing before the end of August. However, I will ship out cases throughout the process, so most of you will receive before that.

Risks and challenges

I have already printed many cases for friends with no issue. I might need some more testing for samsung and nexus phones for best fit, other than that the case has no problem. Customizing tags might be time consuming and requires clear communication with bakers, this might end up taking longer than I thought, but two months is more than enough to overcome this issue. The only thing that I am uncertain about is the packaging box, I found many company that make such box, however I personally have no experience in that and I can't guarantee the box to be exactly the same as the picture I drawn. I will do my best to make the packaging box as nice as possible.
