LEGO F1 Collectable Race Cars Stand

A simple display stand for up to 2 LEGO F1 Collectable Race Cars. There are two bases, one with two compatible lego studs on and one without, so you can either display 1 car per stand or two. You could, if you wanted, display a car and a minifigure. 

This is my first build, so it may not be 100% perfect. Open to feedback!

Edit: By request, I've added a 3x4 stand that holds all 12. Print 4 of each stand and the 3x4 base

I printed at 0.2 layer height with a 20% infill and had no issues. The stand push fits into the base. It's a bit tight, but it shouldn't need any glue once in.
