Kyosho Scorpion RC Car Battery door hatch

I am restoring an 80's vintage kyosho scorpion RC car, and in that process I found that some parts were very hard to get a hold of. So, i took measurements off the car, and made workalike parts that fit with my 3d printer. This one is a battery hatch for the bottom of the car. This was made in tinkerCAD, so its pretty simple in terms of geometry.
