Printed at 200% size of the original I remixed this from. This model at 100% scale is approx 18 x 10 x 7.5 inches.
Modified all parts to be snap together. No non-printed parts necessary.
Tracks are snap together and move freely.
Hydraulic cylinders are modified to twist lock together so they have end stops.
Geared axle shaft has a c-clip for axle retention.
All joints use pop in pins.
Some parts were optimized to print without supports. Some parts still need supports, use your best judgement. I printed the track pieces and hydraulic cylinders with supports but most everything else without if I remember correctly.
Haven't gotten time to add a track tensioner and would like to include 8mm skate bearings to make the track move more easily.
All in all a great toy for my son who's three and been beating it up a bit for the last 4 months. Recommend wall thickness be a little thicker than standard. Maybe 1.5 to 2 mm for durability.
