These will fit great for speed champion models along with other care models. What's nice is its not just a lifted floor, but includes 2 floors so you store 2 cars and move both as a single display unit. The wheel stops are great so your model doesn't accidently roll off the display or get destroyed. The modeled details make it easy to paint and weather if you're looking for diorama pieces. Since everything was designed to be assembled, printing is very easy. No supports are needed.
Everything has been organized onto a plate with all the recommended settings so you can just click and print.
