3D Printing Cat Tractors

We bought our first 3D printer in 2020 and recently upgraded.  A great way to learn about printing is to download existing models and print them.  So far I have found a few good Cat tractor models linked below.  These are designed for 1/100 scale, but the details seem to be decent scaled up to print at 1/50 scale.

Holt 75, 120 and 5-Ton:  www.thingiverse.com/thing:3553160 (5-Ton is in 1st file, 75 and 120 are in 2nd file, I found you need to scale to 230% to get them to 1/50 scale)
