Ramp to floor extension for Hot Wheels Ramp and Start Gate

My kids use a makeshift ramp to drag race hot wheels across the living room floor.  Wanted to print them a ramp but the one here is meant to connect to hot wheels track so I designed this piece that will connect to the bottom of the non-elevated ramp to make it go to the floor instead of connecting to hot wheels tracks.

Print as is with a low layer height to minimize stair stepping.  Supports for the connectors may be needed depending on your printer.
