RC Ramp with different angles

My son got himself a RC Car and spent all day playing with it. Later he came to me and asked if I could build him a ramp so that he could do some jumps. I searched for existing ramps and found some who needed way more filament than what I was ready to invest. So I sat down and designed some ramps myself.

The design is far from begin perfect, but they get the job done. I made some different angles (10, 15, 20 and 25 degrees) and printed the 10 and 20 degrees for him.

The 10 degrees is more of a hurdle than a ramp. The 20 degree is more to his liking as the Car really jumps with it. The Ramp is barely wide enough to fit the Car, but it is rather tricky to hit the ramp. I guess I have to print more and combine them with cable ties.

I am open for suggestions and improvement Ideas. If wished I can also upload the fuison file.

I printed them sideways with no supports and got no issues.
