Tested and printed without issues using Cura slicer.

Hello everyone, I've prepared for you this model of the Czechoslovak heavy-duty truck
Tatra T-148 S1 in 1/18 scale with working steering, suspension, dump bed, doors and bonnet.



Along with this model, I have prepared building instructions (PDF), and I recommend following them for the most efficient assembly.

Keep in mind the capabilities of your printer and the printing orientation of certain parts (strength vs. visual cleanliness). Functional parts such as the chassis, shafts, pins, etc.,
I recommend printing "horizontally" to achieve the best durability. On the other hand,
Cabin and other decorative parts i recommend to print in such a way that they look visually best. Sanding and refining each part afterward is required so that everything fits together easily.
I had the print supports set at around 75 % (some parts without supports), but
I recommend considering what is more suitable for you (taking into account the development of 3D printers and slicers).

I have worked on this model for a long time, and it is my first model of such complexity, so please be patient, and do not hesitate to contact me in case of any issues.

And always remember: Print, Dry fit, File, Dry fit again, Glue...

If you like the model, thank you for your support!

Edit 1:
I had to adjust the front suspension file (Suspension_front_V2_bottom_Tatra_148_SDesign) to make it clear where the top and bottom is.
I also switched the names for "Pin_5_for_front_tires_Tatra_148_SDesign" and "Pin_6_for_rear_tires_Tatra_148_SDesign" because they were reversed. The longer "Pin" belongs to the rear wheels and the shorter one belongs to the front wheels.

Edit 2:
I've added the alternative bonnet file (Bonnet_Tatra_138_V2_SDesign) from older Tatra T-138 and modified engine, that you have to replace, to fit the bonnet (Engine_Tatra_138_V2_SDesign), as it's pretty common in czech republic to replacing parts from other trucks.

I apologize for the inconvenience.
