The materials used are minimal since most of this was 3D printed. However, some of the pieces are easier to use common items for. These are listed below:
- 2 Pins / needles / tiny nails
- Rubber band
- Balsa wood (any modelling wood will do)
- X-acto blade
- super-glue (I used JET modeling glue)
Since the files that had printed were not 100% perfectly designed, I had to modify them a little bit with the balsa wood. This is what the extra modelling wood is for.
The total cost for the above-mentioned materials is fairly cheap if you have the blade already. It was about $4 for the glue, $2 for the wood, and I found the rubber bands and pins sitting around my house.
The 3D printing was done through a friend of my family, so I cannot give an estimated cost using other vendors. Images of each of the CAD pieces is provided on this and other steps.
