Update 30/01/2024:

I added a variation to these ramps that has the holes on the bottom so it can be stacked on the supports. 
The trade off is that at the front of the ramp, the holes poke through the ramp.  It doesn't affect them in any way but is not quite as good looking. The originals are still there for those who prefer the clean look

New addition to my hot wheels monster truck stadium pieces. A shipping container for backflips!

It is designed to fit with the ramp set here: https://makerworld.com/en/models/38502

The two pieces are identical other than the pin (m) vs socket (f) options. Print both to assemble back to back!

This model also used an SVG asset from tezar tantular at the noun project - https://thenounproject.com/icon/tread-3657624/
