EDIT:
3rd March 2025: Modified and improved the Slewring motorplate for 3d printed slewring, to remove slop and to prevent the motor-bushing to loosen up. Also fixed a few files in the slewring buildmanual folder. V1.6 to get the update.
5th November 2024: The new DXF files had a mistake in the overcarriage folder, the filetype should now be correct. sorry about that. Added updated DXF files for lasercutting the steel plates.
27th October 2024: Added new and updated DXF files for lasercutting the steel plates.
"Kitten 394 DXF files V2.zip" to get them.
10th June 2024: The 3d printed Track's rubbed on the bottom of the undercarriage because the distance between the bearings was too big, this has now been fixed. (steel chain version is unaffected)
Files fixed in this update is in the "Undercarriage 3d printed tracks" folder. v1.5 to get the update!
26th March 2024: Fixed errors in a couple of files in the 3D Printed Tracks folder. "RGfrontInside.stl" and "RGfrontInsideM.stl" files. The first layer problems should now be fixed. V1.04 to get the update.
25th February 2024: Fixed a big problem with 4 files for the SteelChain undercarriage.
"RGFrontInside.stl", "RGFrontInsideM.stl", "RGFrontOutside.stl", and "RGFrontOutsideM.stl" interfered with the big idle wheel. this has now been fixed. V1.3 to get the update.
4th december 2023: Added the files for a 3d printed SlewRing. (I actually forgot to put those files in the zipfile) v1.2 to get the files.
3rd december 2023: Added two missing STL files for the undercarriage. (the two footsteps on the sides) v1.1 to get them.
2nd december 2023: Added 2d DWG and DXF files for the steel parts. and 3d STEP files for the steel parts. This is for the people who wants to have the steel parts machined or lasercut.
Build yourself a fully electric hobbygrade excavator.
The model is a 1/14th scale 50 ton class excavator.
Printable on a 22x22 buildplate!
Full partslist with links to all the parts you need to get started!
An overview of all the screws needed is also included.
100 page detailed build manual to provide as much information and help as I possibly can!
Customize your build with different options:
-Choose between two width's of the excavator with an additional option for Four different trackpad-widths!
-Choose between 3d printed tracks, or steel chain tracks!
-Two buckets and a ripper is included.
This has been a very big challenge for me to make availiable for everyone, I have tried my best at making all the parts as friendly as I possibly can.
You can also watch the entire build on youtube, and see how I built mine here:

This project is a combination of 3d printing, and metal works. So you will need tools for cutting metal, and drill holes.
I will say that this is a very timeconsuming build, so youll need to be prepared to use some time on it.
You will need alot of different screws and hardware.
This Excavator model is compatible with the electric 40-70 ton quick coupler in my profile here:

IMPORTANT NOTICE:
I do not show you how to setup your controller or how to put the electronics together in the guide.
