top tube bag

thingiverse

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. To secure it to the bike, use the printed stretchy strap and loop it around to two pins on the sides. Then, in the front, cut two more small slits and loop a bit of velcro through them, and around the steer tube. (I didn't use a second TPU strap because the steer tube spins and the TPU is grippy and would twist the bag with it). 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!
