3D printed Chevrolet K20 Crew Cab Pickup(v1.0)
Step by step assembly instructions
Be active!
Hi guys! I have strange statistics. Only 10-20% of people share photos of the process of building a model and the finished model. This is very bad!
The development of these projects takes hundreds of hours of time... For example, I spent approximately 800 working hours on all Hummer/Humvee projects. The Chevrolet projects took a total of 700+ hours.
Since there is not much activity around my projects right now, I cannot afford to develop large projects lasting 300-600 working hours. Therefore, now I am forced to look for ideas for faster projects. For example, both versions of skid steer loaders took me approximately 150 working hours, a mini excavator - 170 hours. Yes, these are also interesting projects, but I could create something cooler and more epic! For example, now, (Spoiler!) I have in development one project of a military vehicle with a bunch of interesting features. For example, the length of this model will be approximately 91cm . It's about 65-70% complete, but I'm in no rush to finish it because I believe that my community is not large enough for such projects right now..
Do you want to see more cool projects from me?
- Publish posts about the process of building a model in my Facebook group and other groups.
- Post on Instagram and Tik Tok.
- Publish the video on YouTube.
- Write articles on forums.
- If you create modifications for my models, publish them on Thingevers or Cults3D.
Thank you in advance!

Before starting the assembly of the axles, it is recommended to prepare the suspension rods. You need 17 ball joints for M4 Screw, 1pcs - M4 threaded shaft 122mm long, 5pcs - M4 threaded shaft 111mm long and 2pcs - M4 threaded shafts 60mm long. To adjust the length of the suspension rods, you can use the 3D printed part from the "Helpers" folder!

Here I used a 15cm servo extension cable
You can solder longer wires for the speed controller or make 10cm extension cords!
It is recommended to place the radio under the right seat and the speed controller under the left. I used a Hobbywing Quicrun 1060 RPM controller, There is also enough space under the seat to place a Hobbywing Quicrun 860 RPM controller.
