Summary

There are three ways to print this.

As single piece:- Please download STL file but there wont be any movements.

Multiple Pieces :- Download 3mf file with Full_dismantled.3mf. Make sure when printing text seperatly, scale it down to 95% so that it will fit without any issues

1. Combined:- I have uploaded a 3mf file ending with combine.3mf. In this the number of parts are greatly reduced by merging them. For BEGINNERS, this would be helpful. You may also use any 3D viewer software like 3D builder in windows to merge components according to your printer and filaments. The sky is the limit for this.

I wish you try different color schems also. Since i am doing a series in yellow, i have chosen this color scheme but i think it would rather splendid in red and grey with black accessories.

I am very thankful to Mr Benoît Lussier for his feedbacks which has helped me refine the model further.

Movements Included

1. Front Dual Wheel Steering - 30 degrees maximum, Ackermann
2. Back Wheel Rotation
3. Front Doors
4. Fire Hose manipulator arm full movments.
5. Side storage compartments

The main body is made hollow to ensure filament savings.

NOTE The tolerances to some elements are zero which has been intensionally provided to friction lock the elements while not in movements. You may have to fine tune the tolerance from your end using scaling funtion in slicer to ensure good fit without compromising movements.This also applies for the pins that make rotation possible between elements. Please proceed with printing all the pins after testing printing a pin and testing the fit of a joint. You should be able to find the adequate scaling factor with this.

The screws to fix the front axles should not be fully tighned as the parts connecting to the wheel should have the ability to spin on the screw.

Supports should be provided as required.

Appreciate the makes uploads.Open for suggestions.
