Rope pole hook

thingiverse

I'd like to create a portable solution for lassoing ropes in trees without branches available for a tarp canopy while camping. To accomplish this, I'm designing a hook device capable of pushing a lasso up a trunk and grabbing onto the loop end to pull it down. The hook attaches to a standard broomstick or paint roller thread (typically ACME 3/4-5), utilizing an existing hardware standard. My current prototype incorporates a 5-meter extendable pole from a Costco snow rake, but the design should be adaptable to similar poles found on Amazon, such as this model: http://www.amazon.com/Mr-Long-Arm-3212-Extension/dp/B00004YUPO/ref=sr_1_2?ie=UTF8&qid=1410223855&sr=8-2&keywords=extendable+pole To manufacture the hook, I've separated it into two STL files, "PoleHook" and its components. You can use these alone or modify them from their original versions if you prefer to make adjustments. To minimize layer separation on the horizontally printed hook portion, I omitted supports during printing. To further reinforce the joint between the hook and the round piece, I applied a thin coat of ABS dissolved in acetone before painting over it. When designing my initial version, I aimed for a 4mm bolt to fit into the provided hole; however, while cleaning it up with a drill bit, I ended up enlarging the hole to 5/16 inches instead. Subsequently, I printed a custom 5/16 inch by 22 mm pin and glued it in place – I've grown accustomed to this setup and recommend adopting a similar approach if you're interested in improving strength and usability.
