BRIO compatible flexible track

These are two flexible brio compatible train tracks with different clearances: one with a tight fit and one with a loose fit.

When I printed these, the tight fit was good for high quality filament with a smooth finish. However they were too tight when I used rough wood-PLA filament. So I created an additional version with a looser fit.

There are already other Brio compatible flexible tracks on Thingiverse. With these I wanted to minimize the impact on the look of the brio pieces and reduce the rolling resistance of wheels on the track (narrow gaps)
