No more Red AT4 Tow Hooks *Pics Inside*

Rather than wrapping, powder coating, painting...opted to design and 3D print some in black. Printing in ASA due to Fl temps.

Nice. Definitely an improvement.

Looks great. I like the more square design.

I designed both and the squared off one looked more proper to me as well.

What is "ASA"?

What is "ASA"?

ASA (Acrylonitrile Styrene Acrylate) is a thermoplastic material commonly used in 3D printing, particularly for functional prototypes, outdoor applications, and parts that need to withstand environmental stress. It is an engineering-grade polymer with properties similar to ABS (Acrylonitrile Butadiene Styrene) but with enhanced weather resistance and UV stability.

Key Features of ASA for 3D Printing:​

1. UV Resistance: ASA has excellent resistance to ultraviolet radiation, making it suitable for outdoor use where exposure to sunlight is a factor.
2. Weather Resistance: It can withstand rain, snow, and other environmental conditions without significant degradation.
3. High Strength and Durability: ASA is strong and tough, providing impact resistance and durability for functional applications.
4. Heat Resistance: It performs well in high-temperature environments, maintaining its integrity under thermal stress.
5. Chemical Resistance: ASA is resistant to many chemicals, including oils and solvents.
6. Matte Finish: It often produces a smoother and more matte-like finish compared to ABS, which can be beneficial for aesthetic purposes.
7. Ease of Post-Processing: ASA can be sanded, painted, and glued, allowing for customization and finishing.

Applications of ASA in 3D Printing:​

• Outdoor Parts: Items like brackets, housings, and enclosures for outdoor use.
• Automotive Components: Parts exposed to sunlight and varying weather conditions.
• Signage: Durable signs that resist fading from sun exposure.
• Functional Prototypes: Test parts for real-world applications.

Printing Considerations:​

• Temperature Requirements: ASA typically requires high extruder and heated bed temperatures (around 240-260°C for the nozzle and 90-110°C for the bed).
• Enclosed Printing Environment: To prevent warping, it is best printed in an enclosure to maintain a stable temperature.
• Ventilation: Like ABS, ASA emits fumes during printing, so proper ventilation is recommended.

ASA is a popular choice for projects that demand robustness, weather resistance, and good mechanical properties. It is an excellent alternative to ABS for applications requiring UV stability.

Thanks! Now, they'd hold up to towing? (Or do they just look cool?)

If there were an easy way to attach a factory, red tow hook through the front lower plastic on my Denali, I'd be all over one.

Its just a cosmetic cover. If I had to tow, I would pull off. They snap/lock into place.

Ah, got it. Very cool.
