Filament:

Models are designed around the use of a strong PLA. For best results use Prusa PLA, Inland Plus, CC3D Max, ( Hatchbox PLA does not test well with my models) 

Glue:

This model does not use glue. Glue can be used if needed to hold in license plate, brake lights and other fine detail work. Screws are used to hold structure of model together.
