Mattos Designs carries a variety of Prop and Motor Accessories for a variety of applications. These 3D printed accessories are made using PETG and were developed and designed by Butch Napier (except as noted)!

3/4" PVC Elbow Joint (sold as a pair)

This fitting allows you to create an adjustable elbow joint between two pieces of 3/4 inch PVC pipe. Great for use in shoulders, elbows, hips, knees or anywhere you need a flat range of motion.

About PETG:

PETG, or glycolized polyester, is a thermoplastic combining both the simplicity of PLA 3D printing and the strength of ABS. PETG is typically used in models that need good shock resistance or some flexibility, like snap-to-fit components. PETG is water-, chemical- and fatigue-resistant. It is also more durable than PLA as well as less stiff. Most importantly, PETG is one of the most UV-resistant filament types available. This ensures tht the mechanical properties of PETG won't be affected by ultraviolet rays even after years of exposure.
