We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

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.

Original maker's notes

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.

Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.

Printing CAT Excavator

For CAT Excavator we would normally reach for PLA — it is the easy, economical default and suits the majority of models. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
