DuckieTank Antweight

This is our house robot DuckieTank its over weight if you print it all at 30% but with a small battery and 5%infill and low wall count it gets under the 150g but ducky be super brittle

4 wheel drive ( 2 per track) gets over the torque issue with N20s over 250rpm yes its essentially 2 drive ends slapped together and tidyed up
print the tracks in tpu single wall no infil at a .4 nozzle or you will need slower n20s for the torque to turn the track more flxable tup may be better but all i had was overture TPU
