top tube bag

prusaprinters

<p>I don't like traditional top tube bags, because they are a bit too bulky for my tastes. This one is printed with TPU filament, using 0.8mm wall thicknesses. The bag itself is really just a simple "box", which is printed totally sealed up. After its printed, take a knife and cut a slit down the middle of the slanted top portion. This gives you squish access to get at whats inside.</p> <p>Print the brace with something stiff, like PLA or PETG. You could use TPU here too if you wanted, and it should work ok, but a stiffer plastic will help the bag hold its shape a little better.</p> <p>To secure it to the bike, drop the brace into the top (after you cut a slit) then push it through the two holes on the side. The beam provides a little bit of rigidity so the bag doesn't deform from the pressure of the elastic strap.</p> <p>Use the printed stretchy strap (or just a rubber band if you prefer that) and loop it around to two pins on the sides. If you have a flat top tube then that should be all you need to secure it to the bike. If you have a more rounded top tube, then you may need to cut two more slits in the front and add a loop around the steerer tube. I used a velcro cable strap for mine.</p> <p>This was designed with on-the-bike snacks in mind. It is not meant to hold something heavier, like a big phone. Just fill it full of peanuts or gummy bears!</p> Category: Sport & Outdoors
