Fexible Treads for geared wheel tracks

These are 2 tracks pieces for the geared wheels i designed.. Additionally I have a 3rd tread piece which fits both tracks..the tread is meant to be printed with TPU flexible filament..i have not printed it in TPU yet. The tread is meant to be printed and glued onto the track pieces. a dab of silicone may do the trick or super glue. 100% silicone works well though.
