Plywood Gremlin 2" mini racer

I was super inspired by the FT Gremlins popping up and at the same time looking for a way to build my own 2" micro racer. For fun, I decided to design my own frame, and populate it with various parts that seemed sensible.
I've broken a few frames already, but I guess that's what you can expect when they are made of plywood :P With the current frame design, it seems to hold up pretty well!

I can share my frame design if people are interested, might experiment with 3D-printing the concept as well.
