Rollerblade Brake

prusaprinters

<p>no supports needed. 90% infill</p><p>&nbsp;</p><p>Had a silly idea that actually kinda worked out: Trash PET 3D printed rollerblade brakes!&nbsp;</p><p>I rollerblade a lot on VERY ROUGH ROADS in the rainforest. My brake pads die quickly and shipping+replacing is annoying. Now i can turn old bottles into new pads!</p><p>&nbsp;</p><p>You can, of course, use a rubber filament like TPU to give you better performance like a normal skate brake, but i wanted to see if i could turn garbage into a brake pad.</p><p>A challenge was making it strong enough. My first test just had 10% infill and eroded completely halfway down a steep hill (not very fun). But 90% infill now is a big difference!</p><p>Maybe someone will have good suggestions for infill patterns that will be best for braking? or ways to make composite materials?</p><p>To recycle trash to make this PET filament, i built a&nbsp;</p><p><a href="http://recreator3d.com/">http://recreator3d.com/</a> and used my stringer ( <a href="https://www.printables.com/model/221589-motorized-plastic-bottle-string-slicer">https://www.printables.com/model/221589-motorized-plastic-bottle-string-slicer</a> ) to turn trash into filament!</p><p>Now i can print all day!</p><p>&nbsp;</p><p><strong>Microplastics</strong></p><p>Of course the very first thing someone is gonna get grumpy about is MICROPLASTICS. HOW DARE YOU TURN PETROLEUM PRODUCTS INTO ROAD DIRT!!</p><p>But i think people don't understand "rubber" in tires and brakes is a kind of plastic polymer too! often made from styrene and butadiene, which don't seem a lot nicer than PET (and is yet another way cars pollute) correct me if anyone knows better, but PET seems a lot more inert.</p><p>&nbsp;</p><p>Of course the downside is: this plastic isn't the softest and nicest for braking, but i mostly just use it for going down a couple REAL BIG HILLS which grind through the brake anyway, and it's free and maybe less toxic for the environment?</p><p>&nbsp;</p><p><strong>USE AT YOUR OWN RISK!
