This kit came trough 4 redesigning iterations. Was 4 months in development. And have produced 4,592.7 mcg/dL of cortisol in my body (I suppose). Why though? Isn't this kit is just a pile of a wooden dust pressured flat, and burned down to make shape I decided it to be? Yes, it is... So, I have already designed dozens of different models before. But they weren't for the mass distribution. I was 'half-assing' them quickly, without much knowledge about the model building. Even though they were "half-assed", people seemed to like them. And I even got some money out of them. But this design is entirely different The project consists of a 6 main steps. 1. Draft the design. 2. Make the pieces stick together without a glue 3. Test. Test. Test. Test. Test. Test. Test. Test. Test. Test. Test. Test. Test... +∞ 4. Distribute pieces on a sheets of a plywood. 5. Make the instructions. 6. Pack. And enjoy the continuation of the human species. Draft the design -- Easy-peasy. Make the pieces stick -- Brain-my-squeezing. To make the model be any kind of decent to build, it has to have pieces that are not too hard to join, and also are not too easy, so the model becomes loose. This sweet spot was very hard to find. (reason why there is so much testing) No mater how I tried to change the design, what compensation I set - one problem persisted. Some pieces were too hard to join, others - too easy. I blamed my laser for being inaccurate. I blamed my plywood for not having the right thickness. I blamed the world for making me such ugly son of a gun. The problem was... Leonardo da Vinci... If you try to cut out a hole in a piece of wood, and then have a piece that should come in that hole. Then, the bigger the hole, the harder it is to put the piece in. Because bigger holes will have bigger surface area with a piece. Bigger surface area equals higher friction. Higher friction equals difficulty joining pieces. Difficulty joining pieces equals sad me. The solution was - make the holes wider (length stays the same). So the face sides of the "sticking in" piece will not touch the long sides of the hole in the "hole piece". Only the smaller 'edge' sides will. Finally, the model assembles nicely. Now I can test different combinations of colors. And paint the design. The colors I choose you can see on the photos. Distributing the pieces on a sheets of plywood wasn't that hard. I changed the distribution about 4 times. All you need to know is that at first, there was only 5 bigger sheets on which the design was distributed. Then 7 smaller sheets. Then 7 , but more optimized. And now it's 10. I really like when there is a lot of small sheets, rather than a few big sheets. If the sheets are smaller, so will be the box. If the box is smaller then it'll have less chance of being damaged. Win for me, win for the model, win for you. The annoying part is adapting the instructions and the box to the new distribution. I've designed the box myself, and it actually have 6 different variants. Boxes are easy. Not much to say here. The instructions are just the images of the steps in which the model assembles.
