While many ramps already exist on Printables, none met my specific needs. The ramp, in particular, had to be higher on the right side than the left.
Therefore, I've created a fully parameterized version in FreeCAD. You can adjust the width, length, and the height for both the left and right side.
I printed it using PETG. The design includes holes for a connector, allowing you to print it in multiple parts if you require a longer ramp.
The author marked this model as their own original creation.
