80/20 FTC Hook 2015-2016

The team from our FTC group is currently using a clever pull-up tool on the mountain that also doubles as an advance system. However, we need to make sure we post about this innovation on the FTC forum first to verify its legitimacy in competition settings. At our recent event in Roseburg, OR on November 7th, a field judge gave us the thumbs up for using it within tournament guidelines. One of its standout features is a specialized top surface designed specifically to accommodate a servo that can send an all-clear signal when activated. The device comes in two versions. Version 1 boasts narrower inner dimensions perfect for grabbing hold of a pull-up bar, measuring just 1.2 inches across. On the other hand, version 2 sports a wider interior suitable for larger pullup bars and includes an extra pair of mounting holes to secure it even further - this design element allows it to grab securely with its expanded 1.6-inch span. As for print settings, our crew found that employing certain settings allowed them to create durable hooks resistant to impact. We opted for using rafts, supports doesn't really make a difference here and kept the resolution at a sharp 200 microns to ensure every detail was precise. When it came to infill density, they experimented with varying percentages until finding success at a relatively low density of 75%. To their delight, they discovered that even when printing with only 50% infill, their hooks remained remarkably durable and could withstand multiple crashes onto the ground without sustaining any significant damage.
