Were you a teenager and a car enthusiast around 2005 ish? Well, then you’re just like us! NFS M3 GTR We Forever Love YOU 😀
As always we let you be the judge to tell how well we could capture it.
Our aim was to get it as much authentic as  possible.

Chassis v.2.1 (BMW M3 GTR)

This is a Legacy Chassis! Click to v.2.3

Chassis dimensions

Wheelbase270mm
Front Wheel Track183mm
Rear Wheel Track183mm

In the name you can see v.2.1 this means it is our 1st generation chassis system the U profile based one.

We strive for an ultimate universal chassis because we wanna use it under many 3D printed car bodies. So that’s why we created the slideable parts.
The chassis is built on a 2 (aluminium) U profile (8×10 mm) with bought and 3D printed parts.
3D printed parts: Housing of the electric motor, housing of the battery, most of the steering system…
Bought parts are:
 The suspension (length 60 mm), the different wheel rims with the tires, the servo, the receiver, drive shaft and the differential is from Tamiya, the electric motor (17000 rpm), and of course screws (M2, M3) and the ball joints (M3).

Assembly

Here are the bigger body parts

mfactory33.com

Most used tools

Scalpel&Allenkeys&RASPs

Scalpel for removing print support. Keys for screws. Every kind of Rasps to get the surface smooth and even.

Most Used Parts for Assembly

Super glue

Both Gel and Liquid ones. Use GEL when putting parts together. When it holds use LIQUID on the surface.

Super glue for assembly

Glue Gun

It’s adhesive sets very quickly. We used it only inside the body kit, because on the surface leaves nasty traces.
