Project goals
Create a ramp that can be hit at decent speeds, and also fold up into a thin strip of wood.
The internet does not have much information on this, nobody has really made a folding ramp such as this.
Inspiration for the ramp comes from` mtb hopper ramps, they cost on average 600 dollars, made of complete plywood, and fold up.

Design Faze
During this period I design the ramp and plan out my materials. A big problem I faced while designing was how to form the ramp in order for it to fold up perfectly.
This allowed me too figure out a total cost of around 150 dollars.
I 3d printed a model of the ramp as a visual. There is one spot I predicted that would buckle under the stress, so I planned out an extra piece
The model of the 3d printed ramp. in the middle it is visible the in the middle the is no supports going all the way which may allow the surface to buckle and move around.

Bringing the ramp to life
The final pieces
After I had finished cutting my main pieces, I decided to create side support or braces. These I decided to add because it would make the ramp heavier while hitting it, generating a safer ramp. Also the extra support was added in order to keep side to side move movement from happening. The cnc router was not used, but instead, table saw, miter saw, plainer. I used 2 by 4's, 2 by 6's, and extra plywood to create the braces
The Assembly
All the parts were brought home to be routed using handheld router. I used door hinges in order to allow it to fold up. It takes around 10 seconds to go from folded to unfolded stage
Videos and demonstration of ramp use
this semester on this particular project I learned 3 main things.
1. how to cut out material on the cnc router
2. how to 3d print
3. how to design a more complex design in AutoCAD and then make it real
