Before I started, I had to figure out how many layers of card stock (8) I needed so that the house key would slide freely inside the housing. I ...
Blueprint 1: This was the first concept design i made. It had a lot of complexity to it. The plan was to have two buttons on each side that you ...
Blueprint 2: Then came the second attempt at a design. It had the same complex mechanisms and moving parts as the first blueprint, but the desig...
Blueprint 3 - 4: These were a couple of brainstorms I came up with after. Again their design made it prone to errors because I ignored the fact ...
Blueprint 5: This is where I discovered the Halo series OFT switchblades and I tried to make my design look similar because of how good they loo...
Blueprint 6: This was just a revision of blueprint 5, which eliminated the errors that I was able to find. Blueprint 6 (Image 2): This im...
Blueprint 7: The final design concept created. I scraped the magnet push button for a spring slider instead. The idea behind this blueprint is t...
The first step in the build process for me was to hand draw every piece onto card stock based on the final blueprint I made. There was 24 pieces...
Once I had every piece drawn out I started cutting them out. Image 1: Eight pieces that make up the bottom section. The pieces are gradua...
Now I had to use my exacto knife to cut out the excess pieces within each piece that I did not need. I started with cutting out the eight layers...
I continued cutting the excess pieces out for the eight layers that make up the bottom section. ______________________________________________...
The final section that I had to cut was the eight layers that make up the top section. Image 2: Why are the pieces slightly different fro...
Now that the cutting portion of the build process is done, I can now start gluing the layers together. I started by taking the three bott...
Next I took the eight layers that make up the key housing and started gluing them on to the three bottoms layers that I glued together in the pr...
Then I took the remaining bottom layers and glued them onto the backside of the three bottom pieces (now joined with the key housing). Yo...
Next I grouped the top layers into sections and I glued them together. _______________________________________________________________________...
So before I go on, I should probably explain how it's all going to work before I close it up. Image 1: This is the closed position. The s...
This is what I have completed so far. The bottom and housing sections have been joined together, and the top layers have been grouped together. ...
I took the finished bottom section that was combined with the key housing section and glued the first section of the top layer together. I had t...
I also got the release mechanism assembled and put into place. _______________________________________________________________________________...
Then I glued another piece of the top section on. Image 2: I had to glue another section of the release mechanism on. It protects the tin...
I glued another piece of card stock so that I could get a grip when moving the release mechanism. I also coloured it with a black sharpie as thi...
Now it was time to put the two springs that propel the house key out in. I super glued the two springs together before I put them in. ________...
Then I took the last top section and glued it on, closing everything off. ____________________________________________________________________...
It's getting really close to the finished product, but I just have to add a few more things. _________________________________________________...
I took a strip of 0.5cm card stock and wrapped it around the outer edges to give it a refined look. I had to cut openings for the house key and ...
When I tried to push the key back into the housing, I found it a little difficult and it kind of hurt my nail. So I created this index card thin...
The final step was to add the hand made Yin Yang symbol into the circular hole that I made. It was kind of like the "icing on the cake" for me. ...
After around eight months of planning and prototyping I finally came to this, the finished product, completely made out of paper and a few sprin...
Here are some videos of me giving you a look around and showing it in action. The very last video proves that it can actually unlock a door...
