About this print
A scale model of a Caterpillar-style excavator with a custom body, lower chassis and cab shaped to resemble a CAT machine. The boom arm is designed to accept a standard-size servo motor, and printed bushings are included in place of track bearings. The model assembles from multiple printed parts and suits hobbyists interested in functional scale or remote-controlled builds. PETG is a sensible material for the moving components, offering good layer bonding and reasonable resistance to wear.

This is a remix of the original excavator that was from a volvo and it didn't look so good, so i just changed the body, lower body and the cabin so it look more like a Caterpillar.
Also i made it to fit a standard size servo for the boom, i used a 12 kg/cm servo from Hobby kin wich is enought
I also modelised bushing to fit at the place of the bearings in the tracks, it work well and i didn't want to buy bearings for something i played with like 5 time
For track and other boom servo you can buy 4.5 kg/cm servo at 3.50$ each on hobby king.
