Crawler Track Build - American HC230

[Pricer]

Is this a reasonable way to design a crawler track tumbler for a scale model? Is cast-able resins strong enough to make this part? 3D printing? Any ideas will be appreciated. I did order a track shoe that is 3D printed and a few boom parts. I am hoping they will make good master patterns for casting resin. The only thing better than first hand experience is someone who has already experienced it.
